    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

      You are talking about distinct prime factors but the question is asking about number of prime factors

    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.

      This is not a prime factor ....it is a total no of prime factor..2,2,2,3 = 4

  • @harshmellow151
    @harshmellow151 5 місяців тому +2

    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
