((2m)/n^2)^4 = (16m^4)/n^8

You must apply the outside exponent to everything inside the parentheses.

((2m)/n^2)^4 = (2^4m^4)/(n^2)^4

We have to repeat the procedure with the denominator.

(2^4m^4)/(n^2)^4 = (2^4m^4)/n^8

So

((2m)/n^2)^4 = (2^4m^4)/n^8=(16m^4)/n^8

The answer is (16m^4)/n^8.

Explanation:

((2m)/(n^2))^4

((a)/(b))^x=(a^x)/(b^x)

(2m)^4/(n^2)^4

(a^x)^y=a^(x*y)

(2m)^4/(n^(2*4) =

(2m)^4/n^8

(ab)^x=a^xb^y

(2^4m^4)/n^8 =

(16m^4)/n^8
