No because the square root of 2.25 is 1.5 which is a rational number
It is 15 which is a rational number
The square root of 94 is 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.
The square root of 12 is an irrational number
The square root of 0.144 is an irrational number
The square root of 225 is 15, which is NOT an irrational number.
It is 15 which is a rational number
Neither, it is an imaginary number and imaginary numbers are neither rational nor irrational.
No, the best way to figure this out is to plug into a scientific calculator and if the answer you get has a square root around you know its irrational.
If you mean the square root of 196/225 then it is 14/15 which is a rational number because it can be expressed as a fraction.
The square root of 94 is an irrational number
The square root of 200 is irrational.
No, the square root of an irrational number is not always rational. In fact, the square root of an irrational number is typically also irrational. For example, the square root of 2, which is an irrational number, is itself irrational. However, there are exceptions, such as the square root of a perfect square of an irrational number, which can be rational.

It is a irrational number. Because the square root of every imperfect square is irrational number.
The square root of 225 is 15.
