The square root of 225 is 15, which is NOT an irrational number.
225/7 is an irrational decimal, so 225 is not a multiple of 7.
An irrational number.
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
When added to a rational number, any irrational number will produce an irrational number.also, when added to an irrational number, any rational number will produce 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.
-225 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
225/7 is an irrational decimal, so 225 is not a multiple of 7.
No because 225 is an integer and all whole numbers 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.
An irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
The sum of a rational and irrational number must be an irrational number.
No, 3.56 is not an irrational number. 3.56 is rational.
rational * irrational = irrational.
