The square root of 25 is 5, which is a whole number, an integer, a natural number and a rational number.
Yes. The square root of 81 is 9 - a natural number and all natural numbers are rational numbers.
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
It is none of those because the square root of -9 is an imaginary number but the square root of 9 is 3 which is a rational integer or whole number
Yes, the square of any rational number is also a rational number.The square root of 2 is not a rational number.
Yes. 81 is a:- Real number - Rational number - Integer - Natural number - Counting number - Square number - Odd number
The square root of 29 is an irrational number.
No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.
The square root of 121 is rational, an integer, and a natural number.
Another rational number
No. A square root of 36 is -6 which, being negative, is not a natural number.The square root of 36 is 6 ... also rational.
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).
