Is the square root of 22 a rational number?

Answer 1

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

Answer 2

The square root of 22 is NOT a rational number. There is no integer which when multiplied by itself gives 22. Thus, it is not a perfect square. A number is a rational number if it is the quotient of two integers. :)
