The sum of a single number is itself. So the only number whose sum equals 2 is 2.

The area is equal to length x width. Both length and with of a square are the same. The only number multiplied by itself that equals an area of 49 is 7.
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.

Due to the property of uniqueness, the only whole number that equals 25 is 25 itself!
No, consider the number 4 or 16 or 36 for example
No it's not a square number but 127 is a prime number because it has only two factors which are itself and one
The area is equal to length x width. Both length and with of a square are the same. The only number multiplied by itself that equals an area of 49 is 7.
The square of any prime number has only three factors. Example: 121 is the square of 11, a prime number. The only factors of 121 are 1, 11, and 121 itself.
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.
In all of math and arithmetic, past and present, there is only one number that equals 153. That number is . . . . . wait for it . . . . . 153 itself.
No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.
No 7 is not a square number but it is a prime number because it has only two factors which are itself and one.
