Yes, it's 10.
The square root of 5 squared is 5, which is a rational number.
Yes because the square root of a 100 is 10 which is a rational number
When the whole number is a perfect square, ie it is a whole number squared.
Yes, 225 squared is a rational number.
They are rational.
No because 7 squared equals 49 which is a rational number but the square root of 7 is an irrational number
No; the square root of any rational number squared is that rational number. Examples: √(2^2) = √4 = 2. √((1/2)^2) = √(1/4) = 1/2
The square root of 100 is rational since it is not repeating.
No. The square root of any rational number squared is a rational number. eg √(2^2) = √4 = 2. eg √((3/4)^2) = √(9/16) = 3/4
The square root of 29 is an irrational number.
It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational 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.
