How do you multiply with powers?

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

a² x a² --> 2 + 2 --> a^4

Hi, I’ve got my scribblelings on the topic here. I think the bit you want is at the top.https://1drv.ms/b/s!AokvFO_BUHb2iDZmmktZHXla5t1h

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
