​

Answer 1

Answer:

$\sqrt{5} \times \sqrt{15} \times \sqrt{3} \\ \\ \sqrt{5 \times 15 \times 3} \\ \\ = 5 \times 3 \\ \\ = 15$

Answer 2

$\\ \rm\longmapsto \sqrt{5}\times \sqrt{15}\times \sqrt{3}$

$\\ \rm\longmapsto \sqrt{5\times 15\times 3}$

$\\ \rm\longmapsto \sqrt{5\times 5\times 3\times 3}$

$\\ \rm\longmapsto 5(3)$

$\\ \rm\longmapsto 15$
