The two square roots of the number, '169', are +13 and -13 .
16, which is the square of 4, is a two digit even number.
The answer to this question confuses me. The square root of two is an irrational number, so obviously if the square root of two is squared it becomes two which is a rational number. Thinking of it that way then the answer is yes, the square of an irrational number can be a rational number. But . . . You had to know beforehand that the irrational number was the square root of another number. If you start out with an irrational number such as Pi you cannot square it because you cannot know the entire number in order to square it.
9, the square of 3, and 4, the square of 2
The quotient when the square root of a number n is divided by two?
no 81 is a square number the next square number is 100
No. The square root of two is an irrational number. If you multiply the square root of two by the square root of two, you get two which is a rational number.
81 and 100

16, which is the square of 4, is a two digit even number.
No, because the square of a number is that number times itself, so a no two numbers will have the same square.

25 is a square number, and the sum of 9 and 16 is 25. 9 and 16 are also square numbers.
