An irrational number cannot be expressed in the form p/q whereas a rational number can be expressed in the p/q form. Rational numbers have either a terminating decimal representation or a nonterminating but recurring/repeating decimal representation whereas irrational numbers have a nonterminating and nonrepeating decimal representation. Since sqrt(127) is a nonterminating and non repeating decimal expansion, the given number is an irrational number.

this is what they are looking for irrational, because 127 is not a perfect square
