I would just like to know how to do the following things:
-Change radicals from whole to mixed and vice/versa.
-Exponents like (5^-1)^4 and how to solve them.
-How to use the Pythagorem Theroem properly.
-And something called simplifying algebra (this is the thing that I don't get the most)
Example question: (a+b)(2a^2-2b) Simplify.
Hopefully you guys could help me understand this stuff :P
