Question

What value is an irrational number

Answer 1

Answer: Choice A

Step-by-step explanation:

The number
`√(8)` is irrational. We cannot write it as a ratio or fraction of two integers. This is because 8 isn't a perfect square.

Multiplying any irrational number with a rational one leads to an irrational product.

In short:

irrational*rational = irrational

Therefore, the perimeter
`4√(8)` is also irrational.
