Question

Which expressions are equivalent to the given expression?

Answer 1

A.
`2√(10)`

E.
`40^{(1)/(2)}`

Explanation:

`√(40)` can be factored as:

`√(4 \cdot 10)`

`√(2 \cdot 2 \cdot 10)`

This can be simplified to:

(A.)
`2\sqrt{10`

Square roots can also be represented with an exponent of 1/2, hence (E.)
`40^{(1)/(2)}`.
