X is greater than 5. If X were equal to 5, X-5 would be 0 which has no real square root. If X were 4, X-5 would be -1 which has no real square root, and so on.

Can a number with a square root be a real number?
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.
What is the real number root of -25?
There is no real number [square] root of a negative number. There is a real cube root and a real fiftth root etc, but root, by itself, implies square root.
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.
Why is the square root of any real number is always sometimes or never positive?
Sometimes.The square root of a positive number is positive.The square root of zero is zero.The square root of a negative number is a complex number - if you want only real numbers, you can say that it is undefined, and many calculators will give you an error message.
Is the square root of negative 11 a real number?
No. In general, the square root of a negative number is an imaginary number, which is not a real number.

Is the square root of 7 a real number?
The square root of seven is a real number, but it is not a whole number.

Is the square root of 0 a real number?
The square root of 0 is 0, which is a real number.
Is 2i a real number?
No. i = square root of -1, and therefore imaginary. Only by squaring i can you have a real number.
Is the square root of 3 a real number?
Yes, the square root of 3 is a real number. (It is not imaginary. The square root of a negative number is imaginary.) The square root of 3 is not a rational number. It cannot be written as a fraction.

Is the square root of 81 a real number?
Yes. It's 9. The square root of every positive real number is a real number.
Is the square root of negative 11 a real number?
No. In general, the square root of a negative number is an imaginary number, which is not a real number.
How do you do a square root of a negative number that is not a perfect square?
The square root of a negative number is not real.
Is the square root of 95 rational irrational or not a real number?
Since 95 is positive, its square root is real. Only negative numbers have non-real square roots. That leaves the question of whether it is rational or irrational. An integer's square root can only be rational if it is itself an integer. But 95 is not a perfect square, so it's square root is not an integer. Therefore the square root is irrational.
