How do you simplify n^-5 using only positive exponents?

Mar 6, 2018

$\frac{1}{n} ^ 5$ from the exponents rule

Explanation:

When learning your indices/ powers, one of the first rules you learn is
${\left(a\right)}^{-} n$= $\frac{1}{a} ^ n$

let's say i asked you to divide $\frac{{4}^{0}}{{4}^{3}}$, essentially would be intuitive to do is to subtract the powers, ${4}^{0 - 3} = {4}^{-} 3$ ,
so ${4}^{0} = 1$
therefore ${4}^{0 - 3} = \frac{1}{4} ^ 3 = {4}^{-} 3$
