4.6 is rational.

The square root of 16 is 4 which is a rational number

The square root of a composite number is not always an irrational number. e.g. 4 is a composite number and its square root is 41/2 = 2, which is rational 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.

No, it is not. Root 12 = root 4 * root 3, which is the same as 2*root 3. And you should already know than root 3 is irrational.
