Answer 2

Answer:

√3×√5×√15=15

Step-by-step explanation:

$\\ \sf\hookrightarrow \sqrt{3}\times \sqrt{5}\times \sqrt{15}$

$\\ \sf\hookrightarrow \sqrt{3}\times \sqrt{5}\times \sqrt{3\times 5}$

$\\ \sf\hookrightarrow \sqrt{3}\times \sqrt{5}\times\sqrt{3}\times \sqrt{5}$

$\\ \sf\hookrightarrow \sqrt{3}\times \sqrt{3}\times \sqrt{5}\times \sqrt{5}$

• We know that
• √a×√a=a

$\\ \sf\hookrightarrow 3\times 5$

$\\ \sf\hookrightarrow 15$
