B.
12x^9
C.
4x^6
D.
64x^9

Answer 1

\[V=l^3,\qquad l =4x^3\]

What is \(V\) in terms of \(x\)?

Answer 2

\[V=\big(4x^3\big)^3 = \quad . . .\]

Answer 3

64x^27

Answer 4

The index laws you have to use are
\[(xy)^m=x^my^m\] and \[(x^m)^n=x^{mn}\]

Answer 5

64^9 ?

Answer 6

you didn't type the x , but i know what you mean , and that is right
