If the radicals have the same index,
a) then, multiply the coefficients
b) multiply the radicand
⇒ they have the same index, 3
a) (5) (1) = 5
c) The answer is
If the radicals are not similar, not having same index:
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.
