Correct Answer is 5.6×10⁴ Explanation 👇 5.8×10⁴ - 1.5×10³ = 5.8×10⁴ - 0.15×10⁴ = (5.8 - 0.15) × 10⁴ = 5.65 × 10⁴ Since 6 is an even digit placed just before digit 5, Therefore, After Rounding off the correct answer will be 5.6×10⁴
Answer = 5.6×10⁴ Solution = (Given) 5.8×10⁴ - 1.5×10³ Changing 1.5×10³ into 0.15×10⁴ (without disturbing the order of significant figures as ALAKH SIR said - 46:26 ) Now 5.8×10⁴ - 0.15×10⁴ (5.8 - 0.15)10⁴ 5.65×10⁴ Now rounding off at, least decimal place we get 5.6×10⁴ (no change in magnitude 10⁴ while doing rounding off process) ..... 😊
The answer of addition And subtraction is:- 5.8*10^4 -1.5*10^3 =5.8*10^4 -0. 15*10^4 =10^4(5.8-0.15) =10^4(5.650) Rounding off to one decimal:- =5.6*10^4 👉Hence solved😇
bhai reply agar ham 10^3 common leke@- 10^3. (5.8*10-1.5)kare to @--10^3(58-1.5) @----10^3(56.5) @----56.5*10^3 Ho sakta hai ki nahi agar nahi to galat kaha hai
Th way he sings and teaches and crack jokes in between it really shows how he enjoys teaching... what a teacher I wish every school and coaching institutes had one such !!!!
Alakh sir's teaching is best♥️ but I have a doubt sir @53:01 142.06×0.23=32.6728 since we had to round it off to 2 significant figures we cannot write it as 33? Because 33 is a pure no. And 33 has infinite significant figures??? Please tell me if I am wrong ??
u are god for the poor students which cannot afford expensive high quality education ........thnx alakh sir for giving such a quality education at free of cost..u are the best teacher
5.8×10⁴-1.5×10³ We can write 1.5 × 10³ as 0.15 ×10⁴ So, 5.8×10⁴-0.15×10⁴ Take 10⁴ as common, 10⁴(5.8-0.15)=5.65×10⁴ Round off upto to least decimal place means we have to round off up to 2 decimal places ... Then the final answer is - 5.6×10⁴ 👍🏻
Pw ka batch lia hai tab bhi yaha in white board lectures pe jitna smajh me aata hai utna to smartboard par dusre teachers se bhi nhi aata. Love you alakh sir ❤❤❤😂😂

As a Professional Engineer, I often surf the web to see what sites to recommend to our young students. This guy is excellent - and technically correct. Most Hindi RUclips videos are full of errors and bad information. Alakh Pandey is the exception. He is at the same level, or better, than Khan Academy here in the USA.
49:26 ANS SOLUTION. 5.8×10^4 - 1.5×10^3 58000-1500=56500. It can also be written as 5.65×10^4. Ab 5.8 & 1.5 mai decimal places 1 hai tou ans mai bhee ek. Ab 5.65 rounded off to 1place after decimal. 5.650 piche 50 hai aur 5 ke piche even hai isliye jaisa hai waisa hee rahe ga. In short 5.6×10^4(5=5 followed by 0,and 6 is even).
5.8×10000 We should convert it into 58×1000 Bcz we can't subtract unlike terms Now 58×1000_1.5×1000 (58_1.5)1000 56.5×1000 it is correct ans as least decimal place is one🤗
The answer of addition and subtraction question is:- 5.8×10⁴ - 1.5×10³ = 5.8×10⁴ - 0.15×10⁴ = 10⁴(5.8 - 0.15) = 10⁴ × 5.650 On rounding off to 1 decimal place = 10⁴ × 5.6 is the answer 😊😊

5.8x10^4 - 1.5x10^3 First = ten ki power same karte hai Second = 5.8-.15 And some of subtract 5.95 Third = kisbhi number ke baad odd number hoga 1+ hoga Answer = 6.0x10^4
Agar maine itni padh diya na to mere ghar waale mere ko hospital me admit karwa denge aur doctor ko bolenge ki isko Einstein banne ka bhoot sawaar ho gya hai 😂😂😂
I am a physics teacher in international schools including Malaysian, He is one of the best teacher in the world. Any time come Malaysia, 3 days free accomodation and food from my side.thanks
But my answer ; 4.3 × 10³ Unit nhi diya toh convert kyu kare Direct subtract kare toh 5.80000 - 1.5000 = 4.30000 Least decimal places = 4.3000 = 4.3 ×10³
@@studyfuntimembbs you messed up the multiplication as well 5.8*10⁴= 58000 and 1.5*10³=1500 And after subtraction it's 56500 which is equal to 5.65*10⁴ which after rounding off is same as 5.6*10⁴.

Correct answer- 5.6×10^4 Solution- 5.8×10^4 - 1.5×10^3 5.8×10^4 - 0.15× 10^4 ( here during changing 1.5×10^3 into 0.15× 10^3 we keep in mind the number of significant figure e.g two) (5.8-0.15) 10^4 5.65 × 10^4 Now rounding off to two digits, 5.6× 10^4 is final answer 🙌
bhai keep it up. U r smart😎. But waha two significant figure hai isilye two no. nahi liye balki decimal ke baad least two no. hai isiliye liye. Bhai maan pe mat lena maine sirf bataya tumko. Sorry for it

Correct Answer is 5.6×10⁴
Explanation 👇
5.8×10⁴ - 1.5×10³
= 5.8×10⁴ - 0.15×10⁴
= (5.8 - 0.15) × 10⁴
= 5.65 × 10⁴
Since 6 is an even digit placed just before digit 5,
Therefore, After Rounding off the correct answer will be
5.6×10⁴

5.8×10⁴-1.5×10³
We can write 1.5 × 10³ as 0.15 ×10⁴
So,
5.8×10⁴-0.15×10⁴
Take 10⁴ as common,
10⁴(5.8-0.15)=5.65×10⁴
Round off upto to least decimal place means we have to round off up to 2 decimal places ...
Then the final answer is -
5.6×10⁴

As a Professional Engineer, I often surf the web to see what sites to recommend to our young students.
This guy is excellent - and technically correct. Most Hindi RUclips videos are full of errors and bad information.
Alakh Pandey is the exception. He is at the same level, or better, than Khan Academy here in the USA.

ANS SOLUTION.
5.8×10^4 - 1.5×10^3
58000-1500=56500.
It can also be written as 5.65×10^4.
Ab 5.8 & 1.5 mai decimal places 1 hai tou ans mai bhee ek.
Ab 5.65 rounded off to 1place after decimal. 5.650 piche 50 hai aur 5 ke piche even hai isliye jaisa hai waisa hee rahe ga.
In short
5.6×10^4(5=5 followed by 0,and 6 is even).
Bhai pr
Hm
10^4 me he kyu answer la rhe hai
10^3 me bhi to la skte hai.
56500 aya tha
To
56.5 × 10^3
Isme bhi to
1 he decimal place hai
Bhai u are right
49:26 5.65 × 10^4 .... 5 ke pehle 6 tha isliye jaane diya odd hota tha barha deta... 5.6 × 10^4
@@ishivali...naturelover9306 bhai dpp ka 10 sawal hogya ?
@@kumarayush5950 hm
Pr discussion 10^4 pe hai ke
10^3 kyu nhi le
49.27 ans is 5.8 x 10^4 - 1.5 x 10^3 = 5.8 x 10^4 - 0.15 x 10^4 = 5.65 x 10^4..by rounding off we get 5.6 x 10^4
Whole comment section
Your explaination is best
Ty
Right 👍
No only 5.6 is correct.
👍
Thankyou miss riya
5.8×10000
We should convert it into 58×1000
Bcz we can't subtract unlike terms
Now
58×1000_1.5×1000
(58_1.5)1000
56.5×1000 it is correct ans as least decimal place is one🤗
1000 , 100 ho gaye ?
Answer for the question is 5.6×10^4
5.8×10^4 - 1.5×10^3
5.8×10^4 -0.15×10^4=5.65×10^4
On rounding off 5.65×10^4
We will get 5.6×10^4

The answer of addition and subtraction question is:-
5.8×10⁴ - 1.5×10³
= 5.8×10⁴ - 0.15×10⁴
= 10⁴(5.8 - 0.15)
= 10⁴ × 5.650
On rounding off to 1 decimal place
= 10⁴ × 5.6 is the answer 😊😊

Me: my answer is (5.6)10^4, is it correct?
But my answer ; 4.3 × 10³
Unit nhi diya toh convert kyu kare
Direct subtract kare toh
5.80000 - 1.5000 = 4.30000
Least decimal places = 4.3000 = 4.3 ×10³
@@studyfuntimembbs you messed up the multiplication as well 5.8*10⁴= 58000 and 1.5*10³=1500

Correct answer- 5.6×10^4
Solution- 5.8×10^4 - 1.5×10^3
5.8×10^4 - 0.15× 10^4 ( here during changing 1.5×10^3 into 0.15× 10^3 we keep in mind the number of significant figure e.g two)
(5.8-0.15) 10^4
5.65 × 10^4
Now rounding off to two digits,
5.6× 10^4 is final answer 🙌
