SAT exponent problem

obsessedAndreobsessedAndre 219 replies21 threads Junior Member
Here's an SAT type problem.... I don't really understand how they do it.

What is 1/2x^(-1/2) + 1/2x^(-3/2) equal to?

The answer is (x+1)/(2x^(3/2))

I don't get it. I have a feeling it's something simple I'm not seeing. Please help. Thanks.
