Your answer :

(4³)/(4¹) = (64)/(4) = 16

If a number is to be written as a power of another number, it is written with the exponent shown explicitly. Now to be sure,

(4³)/(4¹) = 16

but if we are asked to show the quotient as a power of 4, the base number 4 with the appropriate exponent should appear in our answer.

(4³)/(4¹) = 4^{(3 − 1)} = ?
