Question

Which expression is equivalent to square root - 80

Answer 1

If we simplify √-80 you get 4i√5

Answer 2

`√(-80)=4i √(5)`

Explanation:

We know that
`√(-1)=i`

Here we need to find
`√(-80)`

Let us simplify

`√(-80)=√(-1* 80)=√(-1)* √(80)=i√(16* 5)\\\\√(-80)=i* √(16)* √(5)=i* 4* √(5)=4i √(5)\\\\√(-80)=4i √(5)`
