Question

Un-simplify the simplified radical form. Write as one number under the radical.

Answer 1

In order to "un-simply" the simplified radical form you need to raise the number in front of the radical to the second power
3√2=√3*3*2=√18
-5√6=√25*6=√150
doesn't matter, + or -
24√21=√21*21*24=√10584
