Question

How do you simplify `5n^-3` and write it using only positive exponents?

Answer 1

`5n^-3 = 5/n^3`

Explanation:

Given: `5n^-3` is an expression with a negative exponent.

When any value has a negative exponent it means we are looking at the reciprocal of a fraction. To evaluate the reciprocal we need to divide `1` by the value and change the exponent to positive.

`5n^-3 = 5(n^-3) = 5(1/n^3) = 5/n^3`
