Explanation:
If I interpret the question correctly, we want to find the complex conjugate of:
#-sqrt(-5)#
Note that if
#sqrt(n) = isqrt(-n)#
where
So:
#-sqrt(-5) = -isqrt(5)#
The complex conjugate of a number in the form
So the complex conjugate of
A common notation for complex conjugate is a bar placed above the expression. So we can write:
#bar(-sqrt(-5)) = bar(-isqrt(5)) = isqrt(5) = sqrt(-5)#
