Question 636183: Hi. I was wondering if someone could check to see if this is right or not.
Multiply
(-2m)^2 (3m^9 )^2
I came up with (-6m^9)^4. I ave a feeling I am wrong. Am I? If I am, could you explain how to get to the right answer? I really appreciate it. Thanks

You can put this solution on YOUR website!
(-2m)^2 (3m^9 )^2
----------
= 4m%5E2%2A9m%5E18
= 36m%5E20
---------------
You answer is almost right, but it can be simplified
I came up with (-6m^9)^4
It's (-6m^10)^2 --> 36m^20
