This week in Pre-Calculus 11, I learned how to multiply radicals with the same indexes.
I’ll be showing you how to multiply mixed radicals and entire radicals with the same indexes.
So first, for entire radicals, we simply multiply the radicals together and put it back under a square root. The index does not get changed at all as seen below.
We must then simplify the radical if possible as seen below.
Next, we have entire radicals, we basically follow the same rules as above (multiplying the radicand then simplifying), but this time we multiply the coefficients as well as seen below.
We then simplify if needed. In our case we needed to as seen below.
