Not sure I understand the question. 17 is rational but the square root of 17 is irrational.
It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.
No because the square root of any prime number is irrational inasmuch that it can't be expressed as a fraction.
It is an irrational number and it is about 4.123105626
The square root of 17 is an irrational number. The square root of any number (with the exception of perfect squares, of course) is an irrational number. A rational number is any number that can be represented as a fraction (or ratio, hence the name). So take two numbers, say p and q, whose greatest common factor is 1, and put p over q: p / q. For instance, 0.1 is a rational number, because it can be represented as 1/10. The same can be said for 0.25, 0.190329, and even integers such as 5 (written as 5/1). Irrational numbers can't be expressed as fractions, or ratios, hence their name - it has nothing to do with the sanity of a number! As has been proven elsewhere, pi (3.14159265...) is irrational, as is Euler's number (e). And of course, as I said above, the square root of any number that is not a perfect square is an irrational number.

17 is a prime number with no factors other than itself and 1 therefore minus square root of 17 is an irrational number.

square root of 9 = 3 but 2, 17 and 23 are irrational numbers

No.
Yes they are.
