Question

Classify whether the following Surd is rational or irrational , justify 4√5+ 9

hintHint:

Use properties of rational and irrational numbers.

The correct answer is: irrational number.


    Complete step by step solution:
    4 square root of 5 (It is an irrational number)
    9 equals 9 over 1 (It is a rational number)
    Here one number is irrational and the other is rational.
    On addition, we have 9 plus 4 square root of 5 , we get an irrational number.
    (Since rational number + irrational number = irrational number)
    This cant be written in the form p over q, where p and q are integers.
    9 plus 4 square root of 5 is an irrational number.
