Answer 2

Given: The numbers $\sqrt{81} , \sqrt{25} ,\sqrt{8} ,0.2312$

We have to find the irrational number from the given numbers.

As we know that the numbers which are not rational numbers are stated as irrational numbers.

We have$\sqrt{81} , \sqrt{25} ,\sqrt{8} ,0.2312$.

We can also write these numbers as,

$=>\sqrt{81} =9\\=>\sqrt{25} =5\\\\=>\sqrt{8} =2\sqrt{2} \\=>2.82=>\frac{707}{250} \\\\=>0.2312=\frac{289}{1250}$

Hence, $\sqrt{81} and \sqrt{25}$ are irrational numbers.
