$Aɴsᴡᴇʀ− \\ \sf \green{4 \sqrt{15} \div 2 \sqrt{3}} \\ \\ \sf \implies { \frac{4 \sqrt{15} }{ 2\sqrt{3} } } \\ \\ \sf \: we \: know \: that, \\ \boxed{ \gray{ \sf{ \implies{ \sqrt{a \times b \: } = \sqrt{a} . \sqrt{b} }}}}\\ \\ \sf \: so \: we \: had \: expanded \: 4 \sqrt{15} \: as , \\ \sf \implies \frac{4 \sqrt{5 \times 3} }{2 \sqrt{3} } \\ \\ \sf \implies \: \frac{4 \sqrt{5}. \sqrt{3} }{2 \sqrt{3} } \\ \\ \sf \implies \: \frac{ \cancel4 \: ^{2} \sqrt{5}. \: \cancel{ \sqrt{3}} }{ \cancel2 \: \cancel{\sqrt{3}} } \\ \\ \boxed{\bold{ : \implies \: 2 \sqrt{5} \: or \: 4 .48}}$
