Answer 1

Your answers are all correct, but online one usually uses ^ for powers, so #1 would be written as

5x^2 (2x-3)

also, copy/paste does not do well with special characters, so that's why your exponents came out as they did, and why π didn't show at all.

I had to scratch my head some on #4!

Answer 2

Thank You very much. And Thank You for showing me how to do the exponents.
