Question

Which expression is equivalent to the expression below?

Answer 1

Explanation:

√(-108) - √(-3)

= √(-3*36) - √(-3)

= √[(-3)*36] - √(-3)

= √(-3)*(√36 - 1)

= √[(-1)*(3)]*(6-1)

= i*√(3)*(5)

= 5√3i

Answer 2

A

Explanation:

Given

`√(-108)` -
`√(-3)`

=
`√(36(3)(-1))` -
`√(3(-1))`

= 6
`√(3)` i -
`√(3)` i

= 5
`√(3)` i
