A perfect square root is where the square root of a number equals another whole number. For example, the square root of 144 is 12. 12 is a whole number thus 144 is a perfect square root.

12

The answer is 12, since 12 times 12 equals 144- that is, 12 squared is 144. The square root of a number is that number which when squared gives the given number. Unless the number is a square, its square root will be a decimal approximation.

12 (122 = 144, the closest square root)

Squaring a number is the inverse of square rooting. The square root of 144 is 12, so 12 squared is 144.

It is rational.

sqrt(144) = 12. 12 is the ratio of 12 to 1, so it's nice and rational.

It is irrational, because it is not a perfect square. For example, if you have a number that is perfect like the square root of 100, it would be 10, which is a rational number. An irrational number like 16.4 which would be a not so accurate result like 6.447583839, those are irrational numbers. Hope this helps!

Square root of 1.44 = 1.441/2 = (1.2x1.2)1/2 = 1.2 which is a rational number.

Yes because the square root of 144 is 12 which is a rational number

Irrational. 151 is not a perfect square (144 is the nearest one). square root of 151 is 12.288.

No, it is an integer; all integers are rational.

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.

Not irrational, 12 squared equals 144.

Yes because the square root of 144 is 12

Yes.
