Question

simplify: sqrt60 x sqrt105 (x=multiply)

Answer 1

\[60=2^2\times 3\times 5\]
\[105=3\times 5\times 7\]
\[60\times 105=2^2\times 3^2\times 5^2\times 7\]
\[\sqrt{60\times 105}=\sqrt{2^2\times 3^2\times 5^2\times 7}=2\times 3\times 5\times \sqrt{7}=30\times \sqrt{7}\]

Answer 2

\[\sqrt{15*4}*\sqrt{105}\]
\[2\sqrt{15}*\sqrt{15*7}\]
\[2*15\sqrt{7}\]
\[30\sqrt{7}\]

Answer 3
