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)"

1/2(y10)+y distributive propertys
