you just need to find the factors of 6 in 324
324 = 3*3*2*2*3*3 = 6*6*9
we can have two sixes here. Therefore the answer is 2.
Hope this helps.

I think the answer should be 4
because 324 = (2^2) * (3^4)
6^n can be written as (2^n)*(3^n)
for 324 to be a factor of 6^n... n=4 would be apt..
Plz lemme know your thoughts
