How do you simplify #m ^ 2n^-2#?

1 Answer


If a term with a negative exponent changes position in a fraction, the exponent will become positive, like in this example #m^2/n^2#

In this case, let's start with:


I'm going to rewrite this as a fraction:


The positive exponent in m means it is fine where it is. The negative exponent in n means that if it changes position to the denominator, it will be positive there, like this:
