Question

How do you write `x^3 y^-5` with a postive exponent?

Answer 1

`x^3/y^5`

Explanation:

Recall that:

`1/a^n = a^-n`

This means that `y^-5 = 1/y^5`.

Thus:
`x^3y^-5`
`=x^3*1/y^5`
`=x^3/y^5`

Answer 2

Here we only have to apply 1 law of indices or exponents formula
i.e:
`x^-n=1/x^n`

Explanation:

So now here we have `x^3` `y^-5`,which can also be written as:
`x^3/y^5` (answer)
(note- `y^-5` is in the form of `x^-n` , so can be written in the form of `1/x^n` i.e, `1/y^5`).
