Question

How do you simplify `5a^-1` and write it using only positive exponents?

Answer 1

See explanation

Explanation:

Just to add on, there is a general rule for this where

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

And this is always true if I'm not mistaking

A more complex example would be

`3a^(-4)*b^2*5c^(-7)` which will be rewritten as

`(15b^2)/(a^4*c^7)`
