Can a square of real number is a real number?
The square of a real number is always a real number.
Can a number with a square root be a real number?

Is the square root of 24 real complex or imaginary?
The square root of any positive real number (as in this case) is a real number. (Such square roots are usually irrational.)The square root of a negative real number, such as the square root of -15, is an imaginary, and therefore also a complex, number.
Does every positive number have exactly two real square roots?
Yes, every positive number has exactly two real square roots: one positive and one negative. For example, the square roots of 4 are +2 and -2, since both (2^2) and ((-2)^2) equal 4. However, when referring to the principal square root, it is typically the positive one.
