Yes, at 8:24, Problem 1b should be 16. Sorry for the mistake and thank you for pointing it out!
Bobo
thanks pookie
Very nice. Very very nice.
Nicely and calmly explained.Thank you, Sir.
Why did we subtract in the first two questions and then added the mod to our integer b on the last question
I like the way you explain everything.
the correct answer should be x=16(mod26) Thank you for such a clear representation. Even if you add positive 26 the answer is just same.
Excellent work Sir 🙏🙏🙏
Thankyou. It helps me a lot
man, you're genius!!! The best method ever!!!
Excellent explanation. Thank you.
Can you help me with this, please:x ≡ 2 (mod 11)x ≡ 9 (mod 15)x ≡ 7 (mod 9)x ≡ 5 (mod 7) ?
((d divide n) and (a ≡ b (mod n)) ==> (a ≡ b (mod d))x ≡ 9 (mod 15) ==> x ≡ 9 (mod 3) x ≡ 0 (mod 3)x ≡ 7 (mod 9) ==> x ≡ 7 (mod 3) x ≡ 1 (mod 3)It is impossible.
Kindly make an other video for reaiming questions of problem 4.4 page no 82 itx my humbaly request
Thank so much ...This Video Helped me For Exam time...in 5x=2is 16 not 15 ...sry For Pointing..u
How we can show that 89 | 2^44 - 1 ????
thanks for the video. quite helpful approach!
I don't see the down side because the text is hide the board
At 8:00 we cant divide by 5 because (26 notre prime )
We can divide, cause 5 and 26 are coprime
8:24 did you mean 16?
yes it';s 16 :D

Watch at 1.25 speed. Good video, thanks!

You're the GOAT and a Lifesaver with that one lol
25X=15 mod29 ------------(1)---------------------------- 4X=15 mod29 ------------(2)(1) + (2)X6X=105=18 mod29Ans. 18
how (2) come?
Wonderful! Explained in simplest way. Sir, can you explain 34x≡60 (mod 98) using same technique?
Since 98 is not prime, then this method is invalid
@@doctorscalling9479 21 is not a prime either
• Step 1 - Divide both sides by 217x = 30 (mod 49)• Step 2 - Express 30 (mod 49) as -68 (mod 49)17x = -68 mod (49)• Step 3: Divide by 17x = -4 (mod 49) = 45 (mod 49)
I think you meant x is congruent to 16mod26 in 1.b
Thanks
Adding 26 to -10 is 16 not 15
1b. Please check this:Can x=(-10+26) mod26X=15mod26Or X=15mod26
15 or 16
