As long as the base numbers or letters are the same, powers can be added when multiplying.

a² x a² --> 2 + 2 --> a^4

If the base number is the same, then the powers can be added together.

3^2 x 3^3 =

3^5

However, if the base numbers aren't the same, then you need to make them the same so that you can add the powers together.

9^2 x 3^4 =

(3^2)^2 x 3^4 =

3^4 x 3^4 =

3^8
