Answer 2

$Divide \: 8 \sqrt{15} \: by \: 2 \sqrt{3}$

$\color {Red}{Solution : }$

$= > \frac{ 8\sqrt{15} }{ 2\sqrt{3} }$

$= > \: \frac{8 \sqrt{5 \times 3} }{2 \sqrt{3} }$

$\color {green}{formula : }$

$\color {violet}\sqrt{a \times b} = \sqrt{a} . \sqrt{b}$

$= > \: \frac{8 \sqrt{5} \sqrt{3} }{2 \sqrt{3} }$

$\color {red}cancel \: \sqrt{3} \: in \: numerator \: and \\ \color {Red}denominator \: and \: divide \: by \: 2 \: \\ \color {Red}with \: 8 \: and \: 4.$

$you \: will \: get :$
