Question

Simplify this equation

`4√( - 99)`
​

Answer 1

`12i√(11)`

Explanation:

Simplify:

Split the radical into two factors with a perfect square as at least one factor

`4√(9) √(-11)`

Evaluate the perfect square

`4(3)√(-11)`

`12√(-11)`

Since we cannot have a negative in a radical we need to factor out
`√(-1)` which is represented as
`i`

`12i√(11)`
