Rational.

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

It is rational.

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

144 is rational. It is a whole number, it is an integer, etc.......

144 = 144/1 so it is rational.

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

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

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.

Yes, it is -12 or +12, both of which are rational.

Not irrational, 12 squared equals 144.

No.

Yes because the square root of 144 is 12

Yes.

You are looking for a number which, when squared, gives you 144. Therefore, an obvious method is to try squaring different numbers, until you get one whose square is the desired number (in this case 144), or (in other cases), close enough to the desired number (since any whole number which is not a "perfect square" has an irrational square root).

Yes, 102 isn't a square number (1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144) so the square root of 102 will keept going forever and is irrational.

Yes. It's the ratio of -144 and 4. That makes it a rational number by definition.

Yes. All integers are rational numbers, since they can be written as (in this case) 144/1.

Square root of 144 is 12

Yes

The negative square root of -144 is -12i - that is -12 times the square root of minus 1, ie √-144 = 12√-1. The above is a complex number, which I suspect is not the answer you wanted; there is no real number that is the square root of a negative number If you wanted the negative square root of 144, then it is -12.

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.

the square root of 144 is 12. the 'square root' means what number times itself equals an answer. (144) the answer is 12.

The square root of an answer is a number times itself to get that number so the square root of 4 is 2 the square root of 144 is 12 because 12 times itself gives us the answer of 144

The square root of a number is what multiplied by itself gives you that number For example, the square root of 81 is 9 since 9x9= 81. Another example is 144. The square root of 144 is 12 since 12x12=144.
