Answer 1

Answer:

√45 is an Irrational Number.

Step-by-step explanation:

√45 = √9 x 5 = 3√5

But, we already know that √5 is an irrational number.

We also know that when an irrational number (√5) is multiplied by a rational number (3), the product is always an irrational number (6.7082039324.....).

So, √45 is an irrational number.
