$2 \sqrt{2 } \times 3 \sqrt{3} = (2 \times 3) \sqrt{(2 \times 3)} = 6 \sqrt{6}$

d)

$\sqrt{9} \times 5 \times \sqrt{4} \times \sqrt{1} = 5 \sqrt{(9 \times 4 \times 1)} = 5 \sqrt{36}$

Answer 2

$a. \\ 2 \sqrt{2} \times 3 \sqrt{3} = \\ 6 \sqrt{2} \sqrt{3} = \\ 6 \sqrt{2 \times 3} = \\ 6 \sqrt{6}$

$b. \\ \sqrt{9} \times 5 \times \sqrt{4} \times \sqrt{1} = \\ 3 \times 5 \times 2 \times 1 = \\ 30$
