Question

How to work with negative exponents

Answer 1

remember the exponential rules and treat them regularly

`x^(-m)=(1)/(x^m)`
and

`(x^m)(x^n)=x^(m+n)`
and

`(x^m)/(x^n)=x^(m-n)`

that's baseically all you need to know, as long as you understand the rules
here are some examples

`x^(-3)=(1)/(x^3)`


`(x^(-4))(x^2)=x^(-4+2)=x^(-2)=(1)/(x^2)`


`(x^(-2))/(x^3)=x^(-2-3)=x^(-5)=(1)/(x^5)`
