Question

the problem reads:

evaluate sqrt (-4) if possible.

my answer:

sqrt (-4)<0

therefore this is not a real number

looks correct

you cannot take the square root of a negative number in the real number set.

Have you learned the imaginary number i = sqrt(-1) ??

if so you can do:
sqrt(-4) = sqrt(4) x sqrt(-1)
= 2i

if you have not studied i, then you would say: "there is no real solution to sqrt(-4)"
