# Out of the four options, only one is correct. Write the correct answer.For a non-zero integer x, (x4)-3 is equal toA. x12B. x–12C. x64D. x–64

By laws of exponent,

(xm)n = xmn

In this question,

m = 4

n = -3

(xm)n = xmn

(x4)-3 = x4×-3

(x4)-3 = x-12

Hence, for a non-zero integer x, (x4)-3 is equal to x-12.
