My teacher decided that we needed a review and hit us with Exponents. Well seems he was right. I'm having trouble remembering and simplifying exponents.

The only rules for the problems he's given us is "Leave without radicals or negative exponents"

1. (.1)^2(4xy^2)^2

For this one I...

.01(16x^2y^4)

But from here I forget what to do. Do I distribute the .01 to 16, x^2, and y^4?

The second one I'm having trouble is

3(3^(x/2))^2

Correct me if I'm wrong please...

3(9x^2)

27x^2

Thanks any help is greatly appreciated
