Question

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

Answer 1

Answer:

All options are correct.

Step-by-step 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.$\frac{1}{x^4}$

The expression cannot solve further.

The given expression is in the  simplest form.

C.$\frac{w^7}{x^2}$

$x^2$ 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.$\frac{1}{a^2}+b^2$

The expression cannot solve further.

Hence, the given expression is in the  simplest form.

F.$\frac{1}{b^5}$

The expression cannot solve further.

Hence, the given expression is in the  simplest form.

Hence, all options are true.
