Is the square root of any number an irrational number?

no square root of 9 is 3 which is rational -- to be more specific: an irrational number is a number that cannot be expressed as a fraction. Pi, for example, is one of these numbers. If a number is not a perfect square (4, 16, 9, 144, 225, etc.), then it's square root is likely to be an irrational number. For example, the square root of 2 (1.41421356...) is an irrational number because it cannot accurately be expressed as a fraction.

Is the square root of 12 a rational number or irrational number?

If the square root of a natural number is not an integer, then it is irrational. Another way to look at it: if a natural number N falls between two perfect squares, then the square root of N is irrational.So in this case, 12 is between 9 (3 squared) and 16 (4 squared). So the square root of 12 is between 3 and 4, and also the square root of 12 is irrational.

Which number have no rational square root?

For example, in the case of integers: the square root of a positive integer is either an integer (in the case of perfect squares, such as the square root of 1, 4, 9, 16, etc.), or an irrational number (such as the square root of 2, 3, 5, 6, etc.). Similar in the case of the square root of a rational number (fraction): if you don't specifically choose fractions with perfect squares in the numerator and denominator (e.g., 4/9), you will end up with an irrational square root.
