√17 is irrational
Not sure I understand the question. 17 is rational but the square root of 17 is irrational.
Rational. It can be written as a fraction where the denominator is not equal to 0. For example as -17/1. All integers are rational.
It is a rational number because it can be expressed as a fraction in the form of -17/1
It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.
