jhonyy9 · Answer

use this

$$x^{-2} = \frac{ 1 }{ x^{2} }$$

and

(x^a) * (x^b) = x^(a+b)

Extrinix · Answer

Remember that when multiplying with exponents, you add the exponents together, like Jhonyy is saying.

$(x)^{a+b}$

Vice versa goes for division, in which you would subtract the exponents.
