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.
2:18 - ant high on DIY
U need to make 10= 2*5
Answer becomes 60
yes there is an error
i have one question, please anwer this question :
find total number of prime faktor of 2^12 + 4^12
I'm confused

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
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.

Super
Thanks
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
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
Good explanation dear brother.@@utkarshchaudhary9338
Answer is 60
I think 10 not a prime number how did u do🤔
60 will be the right answer
72
60 ans
60
U need not done prime factors of 10
Question 1st ka answer galat hai
118 correct answer hoga 😊
How u people as a teacher make such irresponsible errors....10 can b divided into 5 and 2...
Glt mt pdao please
Since when multiplying both minus turns out to be minus correct your own maths then teach others dnt b a wannabe
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
Answer is 60 you forget to subtract the power of 2
Total no of factors aise thori nikalte h madm 😂sirf English bolna jannti h aur kuch nhi
All of your calculations are wrong
Waaah y teaching wrong things
60
52
