Re: Help please with Exponents and roots

These are standard textbook problems, no tricks. I'd start by using the rules in the text and studied in class. For example, for #1... (abc)^3 = a^3*b^3*c^3 along with (a^b)^c = a^(bc). Try applying that to problem #1, then we'll take a look at the rest.

If you're having trouble figuring things out from your book and / or your class notes, then please study some online lessons regarding exponent rules and simplifying with exponents.
