HeyMate, when we factorize √8

we get

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

since 2 is two times we can write this as

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

Answer 2

$\mathfrak{\huge{\underline{\underline{\red{Answer:-}}}}}$

$\sqrt{8} = \sqrt{2 \times 2 \times 2 } \\ by \: factorisation \: \\ \sqrt{8} = \sqrt{2 \times {2}^{2} } \\ so \\ \sqrt{8} = 2 \sqrt{2}$

$\rule{200}{4}$
