No perfect square can end in 2.
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.
What do you mean with "the" two square numbers? There are infinitely many square numbers, not just two. Just square any counting number (0, 1, 2, 3, 4, etc.), and the result is a so-called square 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.

Correct!
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.
Multiply the two numbers to get the number of square feet. You end up with 22,500 square feet.

25.9615099... , An Irrational Number- you can carry it out to as many places as you like but never get it exact.Rounded to two decimal places, the square root of 674 is equal to 25.96.
No, because the square of a number is that number times itself, so a no two numbers will have the same square.
