Answer 2

Answer:

$(a) \: 3 \sqrt{5} \times 2 \sqrt{5} \\ = 3 \times 2 \times \sqrt{5} \times \sqrt{5} \\ = 6 \times 5 \\ = 30 \\ (b) \: 3 \sqrt{8} \times 3 \sqrt{2} \\ = 3 \times 2 \sqrt{2} \times 3 \times \sqrt{2} \\ = 9 \times 4 \\ = 36 \\ (c) \: 6 \sqrt{15} \times 4 \sqrt{3} \\ = 6 \times 4 \times \sqrt{3} \times \sqrt{15} \\ = 6 \times 4 \times \sqrt{3} \times \sqrt{3} \times \sqrt{5} \\ = 6 \times 4 \times 3 \times \sqrt{5} \\ = 72 \sqrt{5}$

Hope this helps.
