It is 15 which is a rational number
The square root of 94 is an irrational number
The square root of 11 is an irrational number
If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.
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 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.
