I'm in math class

Basically if something is raised to a negative power then put it on the other side of the fraction line and change the negative to a positive.

If there is no fraction line to start with then draw one in and put 1 on the bottom :)

Here is a post that could help you more:

A negative exponent basically means that the term is in the wrong place: if it is in the numerator, put it into the denominator and make the exponent positive; if it is in the denominator, put it into the numerator and make the exponent positive.

For  c⁶ / c^-7   --->   rewrite it as:  c⁶ · c⁷  =  c¹³.

(Since the exponent is negative and the term is in the denominator, write the term in the numerator with a positive exponent.)

What grade are u in?

Im sure you don't need to know the grade.

Sorry, I just wanted to know if I could help. But if you are in a higher grade than me, then I probs can't. 

\(same, bruh. \begin{pmatrix} 1\\ 2 \end{pmatrix} \begin{bmatrix} 1 && 2 \\ 3 && 4 \end{bmatrix}\)
