Of course, not only can it be a real number but it is a real number. When you take the square root times itself, the result is a number that is real.
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.
