Question

How do you simplify and write `6y^-4` with positive exponents?

Answer 1

`6/y^4`

Explanation:

Since `x^(-y)= 1/x^y`, we can simplify this expression in this manner.

6 does not have an exponent, so it stays on top. `y^(-4)`, on the other hand, does. We can substitute `1/y^4` for `y^-4`.
