Question

please solve this?????????

Answer 1

$solution \: \\ we \: have \: . \sqrt{99} \times \sqrt{396} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = > \: \: \sqrt{99 \times 396} \\ \\ \: \: \: \: \: \: \: \: = > \sqrt{3 \times 3 \times 11 \times 2 \times 2 \times 3 \times 3 \times 11} \\ \\ \: \: = > \sqrt{3 \times 3 \times 3 \times 3 \times 2 \times 2 \times 11 \times 11} \\ \\ \: \: = > \sqrt{3 \times 3 \times 2 \times 11} = 198 \\ \\ so \: ans.is \: 198$
if u understand plzz Mark as brilliant.
