Question

√−100 = ? + ? i I need help please!!!!!!!!!!

Answer 1

we are given

`√(-100)`

we know that

`-1=i^2`

now, we can replace -1

`√(-100) =√(-1*100)`

`√(-100) =√(i^2*100)`

`√(-100) =√(i^2)*√(100)`

`√(-100) =10i`

we can add 0

it does not affect

so, we get

`√(-100) =0+10i`..............Answer
