When multiplying radical expressions of the same power, be
careful to multiply together only the terms inside the roots and
only the terms outside the roots; keep them separate. After
multiplying the terms together, we rewrite the root separating
perfect squares if possible. The rules of distributing and
multiplying binomials (FOIL) apply to radicals as well. Now
we're going to talk about multiplying radicals, so we know how
to simplify radicals okay so behind me I have the square root of
50. We know how to simplify this by saying okay what perfect
square goes into 50? 25 so we can break this down into 25 times
2 which we can then split up again into square root of 25 times
the square root of 2. Square root of 25 is simplifies the 5 so
we're ending up with 5 root 2. Okay, so we're able to split it
up to get a simplified version okay? If we're multiplying two
things like over here I have square root of 2 times the square
root of 8, as long as our square roots are the same so these are
both squares so they're b
