Homework Help: Math- Completely confused!

Posted by Jackie on Saturday, August 21, 2010 at 6:02pm.

Simplify each expression (where possible) and write the answer without using negative or fractional exponents. Assume that X>0.

a. 8x^(1/3)
b. (-8x)^(1/3)
c. (8x)^(-1/3)
d. (3x^(3/4))(16x)^(1/4)
e. (x^(1/2)) / (x^(5/2)

so far my answers are : a.2x b. -2x c.1/2x but i feel that i'm doing it completely wrong. d&e i don't know how to solve them...
Could someone explain how to simplify them? Thank You!
