Question

find the geometric mean of 3 and 15 if necessary give the answer in simplest radical form . please show work thank you

Answer 1

@judith, same as last one
take the square root of the product

Answer 2

rad(3*15)= 3rad5

Answer 3

only part that might not be trivial is to write in simplest radical form, look for perfect squares inside the radical

Answer 4

\[\sqrt{3\times 15}=\sqrt{45}=\sqrt{9\times 5}=\sqrt{9}\sqrt{5}=3\sqrt{5}\]
