Question

27 • a • a • a as an expression?

Answer 1

For this case we have the following expression:

`27 * a * a * a`

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`

Answer:

Rewriting the given expression we have:

`(3a) ^ 3`

Answer 2

the expression is 27a^3 or (3a)^3
