underroot 45 is irrational no.

Answer 2

Answer:

√45 is an irrational no.

Step-by-step explanation:

√45 = √(3 × 3 × 5) = 3√5

∵ the digit 5 is left in under root because it does not have any pair here so, the √45 is not a perfect square and as we know that an imperfect square is an irrational number.
