I'm confused Maam by this method i got total number of prime factors of 72 is 5 because: (2^3 × 3^2 ) so 3+2 =5, but when I checked in the factors of 72 , which are : 1 , 2 , 3 ,4, 6, 8,9,12, 24 , 36 ,72 , there are only 2 prime factors which are 2 and 3 , other factors are not prime so what is happening pls explain
The method to find Prime no. is completely wrong ❌ .... You can check it on any small no.... For example- 12=2^2*3^1 Total prime factors from your method = 2+1=3 But there are actually only 2 prime factors( 2&3 ) of 12... So please someone studying please confirm before you apply any method..
She considers all prime factors as the power they have for example 4 = 2², then one prime factor is 2 and another one is also 2, so total number prime factors is 2 but according to you there is only one (i.e. 2) prime factor for 4
You need to clear the doubts first, then teach us, because your wrong method ruined our exam completely The ans is : 5^10 * 7^10 * 10^-10 * 10^-10 * 3^30 * 5^25 * 2^25 5^10 * 7^10 * 10^-20 * 3^30 * 5^25 * 2^25 5^10 * 7^10 * 3^30 * 5^5 * 2^25 10+10+30+5+25= 80 ans Pls correct me if I'm wrong
at 7:26...(2^5 * 3^30 * 5^15 * 7^10) will give the result 60...But overall a must have topic for competitive exams.
U need to make 10= 2*5
Answer becomes 60
yes there is an error
Great but, In The last question you have to represent 10 power of 5 as (2 power of 5 x 5 power of 5). Then only your formula works.

You are talking about distinct prime factors but the question is asking about number of prime factors
@@devyadav5184can you elucidate it comprehensively sir
Hello
explain me?? You are worng
The method to find Prime no. is completely wrong ❌ .... You can check it on any small no....
For example-
12=2^2*3^1
Total prime factors from your method = 2+1=3
But there are actually only 2 prime factors( 2&3 ) of 12...
So please someone studying please confirm before you apply any method..

24 has only 2 prime factors........ But after doing prime factorisation.... And applying ur trick..... I get '4' why so??
Cause' she told the wrong method
That method is used to get sum of prime factors!
This is not a prime factor ....it is a total no of prime factor..2,2,2,3 = 4
U need not done prime factors of 10
Answer is 60
Super
Thanks
60 will be the right answer
72
60
60 ans
Question 1st ka answer galat hai
118 correct answer hoga 😊
You need to clear the doubts first, then teach us, because your wrong method ruined our exam completely
The ans is :
5^10 * 7^10 * 10^-10 * 10^-10 * 3^30 * 5^25 * 2^25
5^10 * 7^10 * 10^-20 * 3^30 * 5^25 * 2^25
5^10 * 7^10 * 3^30 * 5^5 * 2^25
10+10+30+5+25= 80 ans
Pls correct me if I'm wrong
