What is the product of 5the square root of 3. • 4the square root of 15.? Simplify if possible.

60the square root of 5.
20the square root of 5.
60the square root of 15.
20the square root of 15.

Answer 1

I'm not 100% sure here, but wouldn't you split the square root of 15 to 5 & 3?
So like: \[\sqrt[5]{3}\times \sqrt[4]{15}\]
\[\sqrt[5]{3}\times \sqrt[4]{3}\times \sqrt[4]{5}\]
the 3s cancel, leaving the 5. and the 5&4 multiply leaving it looking like \[\sqrt[20]{5}\] as the answer. Hope this helps (:
