Question

Simplify each expression using Product to a Power Property a. (9a)^2 b. ( 3x)^2

Answer 1

`\begin{gathered} a)81a^2 \\ b)9x^2 \end{gathered}`

1) Let's simplify those expressions making use of exponents rules:

`(9a)^2=81a^2`

Note that the exponent outside the parenthesis is 'distributed' over each term inside.

2) Similarly for the second expression we can state that:

`(3x)^2=9x^2`
