What if the radicals to be multiplied don't have the same index?
Just multiply the index. Then simplify if it can.

If the radicals have the same index,
a) then,  multiply the coefficients
c.) Simplify

Example:
⇒ they have the same index, 3

a)  (5) (1) = 5
b)

If the radicals are not similar, not having same index:
Example:

The first radical has index of 3; the second has 2.

a)  Convert the radical to rational exponents:

b)  Convert fractional exponent to similar fractions; Find their LCD⇒6

c) Convert to radicals then multiply.  The index for both radicals is 6.

d)  Simplify:
