Hello,

If for example to simplify within a complex fraction it has (x+h)-3 is that 1/(x+h)3 or 3/(x+h)?

as (x+h)-1 is 1/(x+h)

Thanks (im pretty sure its the cubed, but just want to make sure).

The example is in my book, but its an even numbered question so the answer isn't in the back.. and there are no examples with negative powers over 1.

The actual question is:

Simplify:

$\displaystyle \frac{(x+h)^-3 -x^-3}{h}$
