Answer 2

Correct Question :-

Evaluate

$3 \sqrt{2} \times 3 \sqrt{3}$

Solution :-

$= > 3 \sqrt{2} \times 3 \sqrt{3} \\ = > 3 \times 3 \times \sqrt{2} \times \sqrt{3} \\ = > 9 \times \sqrt{2 \times 3} \\ = > 9 \times \sqrt{6} \\ = > 9 \sqrt{6}$

or

$= > \sqrt{9 \times 9 \times 6} \\ = > \sqrt{81 \times 6} \\ = > \sqrt{486}$
