No, in fact unless an integer has an integral square root, the square root is always irrational. Note that some rational fractions can have rational square roots, though. Example: sqrt(4/9) = sqrt(4)/sqrt(9) = 2/3, which is rational. Or sqrt(9/16) = 3/4
Some are and some are not. For example, the square roots of 2.25, 3.61, 4, 4.84, 5.29, 6.76, 7.29, 8.41, 9, 10.89, 11.56, 12.25, 13.69, 14.44, 15.21, 16, 17.64, 18.49, 19.36, 20.25, 21.16, 22.09, 23.04, 24.5025, and 25 are all rational numbers. But the square roots of 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 21, 22, 23, and 24 are irrational numbers. We believe, but can't prove easily, that there are more irrational square roots than rational ones.
√479 ≈ 21.89 √500 ≈ 22.36 Making 22 as the integer between them.
4.69
You wont be able to add a rational number and an irrational number and get a number not in a fraction ( 3 + 22/7) (21/7 + 22/7 = 43/7) So, yes as you see in the example above it made another irrational number.
22 square feet. Multiply the two dimensions - the result is the number of square feet.

yes example pi which is ratio of circumference of a circle by diameter. That is a real number which is APPROXIMATED as 22/7 but is not a rational number. Another example square root of 5,6,7. These are all real numbers but cannot be expressed as a rational number (p/q form)
The square root of 2 squared is 2. sqrt(22)=2 The square root function and the exponent 2 and opposite function and cancel each other out. 22=4 sqrt(4)=2 =>sqrt(22)=2 What is the (square root of 2) squared - If you take the square root of a number then square it the answer is the number itself, so the answer is 2! What is the square root of (2 squared) - Looking at the question another way, if you take a number and square it, the square root of the resulting answer is the number itself, so the answer is 2! Unless, of course, this is a trick question . . . ivj
The negative square root of 484 is -22. This is because the square root of 484 is 22, and the negative square root indicates the negative value of that root. Thus, -√484 = -22.
No it is not. 22 is not a perfect square because it is not a product of a rational number multiplied by itself. The closest perfect square would be 25
A Square of a number is when the number is multiplied with itself Ex: 22 = 2 * 2 Square root of a number is a number which when multiplied with itself returns the first number. Ex: Square root of 25 is 5 because 25 = 5 * 5
No it is not. 22 is not a perfect square because it is not a product of a rational number multiplied by itself. The closest perfect square would be 25
No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
-11
No 22*pi is not a rational number
Negative numbers can't be squared rooted but the positive square root of 484 is 22
