Answer is 25 factors.

36^2 = (3^2 * 2^2) ^2
= 3^4 * 2^4

The # of factors is (4+1) * (4+1) = 25.

PS: there is a nice explanation on how to find total # of factors by either Ian or Stuart.

Find the primes for 36 (3^2 and 2^)^2 That is 3^4 2^4

Now the primes will be

1, 2,2^2,2^3,2^4,3,3^2,3^3,3^4 =9 primes and combination of (2,2^2,2^3,2^4,3,3^2,3^3,3^4) that is 4*4=16

9+16 = 25
