Please explain how to do this.

anonymous · Answer

okay do you how to convert a negative exponent to a positive one?

anonymous · Answer

Do you flip the equation?

skullpatrol · Answer

$$\frac{x^3}{x^{-7}}$$

anonymous · Answer

kinda $$x^{-n}=\frac{ 1 }{ x^n }$$

anonymous · Answer

So then what?
Just add the exponents 3 & 7?

anonymous · Answer

yup you got it.

anonymous · Answer

Okay thanks!

anonymous · Answer

also you could have tried subtracting the exponets instead of converting them.$$\frac{ x^n }{ x^k }=x ^{n-k}$$
