Answer 2

$= \sqrt{8} \\ \\ = \sqrt{2 \times 2 \times 2} \\ \\ \sqrt{8} = \sqrt{2 \times 4 } \\ \\ \sqrt{8} = 2 \times \sqrt{2}$

Thus, 2 and 12 are the factors of 18,

Since, 2 is a rational number while v2

is the irrational number,

We can make v2 a rational number

by multiplying v2.

12 is the rationalizing factor of 8.
