Question

Which expressions are in the simplest form? Check all that apply.

(Please help, I've been stuck on this all afternoon)​

Answer 1

All options are correct.

Explanation:

We have to find the expression which are in the simplest form.

A.
`x^(-3)+y^3`

The expression cannot solve further.

Therefore, the given expression is in the simplest form .

B.
`(1)/(x^4)`

The expression cannot solve further.

The given expression is in the simplest form.

C.
`(w^7)/(x^2)`

`x^2` cannot divide
`w^7`.

The expression cannot solve further.

Hence, the given expression is in the simplest form.

D.
`a^(-9)`

The expression cannot solve further.

The given expression is in the simplest form.

E.
`(1)/(a^2)+b^2`

The expression cannot solve further.

Hence, the given expression is in the simplest form.

F.
`(1)/(b^5)`

The expression cannot solve further.

Hence, the given expression is in the simplest form.

Hence, all options are true.
