Is the following computation correct? If not give the correct computation: `[sqrt((-2))sqrt((-3))]=sqrt((-2)(-3))=sqrt(6)`

Explanation

The said computation is not correct,
because -2 and -3 both are negative and

`sqrt(ab) = sqrt(a) sqrt(b)`


is ture when at least one of a and b is positive or zero.
The correct computation is


`(sqrt(-2))(sqrt(-3))= (isqrt(2)) (isqrt(3))=i^(2) sqrt(6) = -sqrt(6)`
