By definition, by ownership of the power:

In the multiplication, if we have the same base the exponents are added, for example:

A (x * x * x) = Ax^((1 + 1 + 1))= Ax ^ 3

Rewriting the given expression we have:

(3 * 3 * 3) (a * a * a) =

$(3^ {(1 + 1 + 1)})*(a^ {(1 + 1 + 1)}) =$

3 ^ 3 * a ^ 3 =

(3a) ^ 3
