Question
Which of the following is an irrational number?
Correct Answer
Option A is the correct answer.
Detailed Explanation
5 + √6 is irrational because √6 is irrational and adding a rational number (5) does not make it rational. √36 = 6 (rational), 22/7 is rational, 0.125 = 1/8 is rational.
Hint
Irrational numbers cannot be expressed as a fraction p/q. √6 is irrational.
