Question

WHich choice is equivalent to the expression below? √-125

Answer 1

Final simplified form is
`5√(5)i`

Explanation:

We have been given an expression
`√(-125)`

Now we need to simplify
`√(-125)` and check which choice matches with simplified form of
`√(-125)`.

You missed to provide the choices but still we simplify that.

`√(-125)`

`=√(-5*5*5)`

`=5√(-5)`

When there is negative sign inside square root then we replace that by "i" iota.

`=5√(5)i`

Hence final simplified form is
`5√(5)i`
