TOTALLY RADICAL DUDE!!!!

Practice with Radicals ADDIT IO N & SUBTRACTION WITH RADICALS Simplify radicand first if possible. If the radicands are the same treat them as variables and combine like terms. Examples: 1. 2 5 + 6 5 = 8 5

2. 2 + 3 − 7 + 4 3 = −5 + 5 3

Or 5 3 − 5

If the radicands are different, they can not be combined. Only those that are alike can be combined. Examples: 1. 2 7 ­ 4 5 = This is already simplified because the radicands, 7 and 5, are different. 2. 3 3 + 5 5 = This is already simplified because the radicands, 3 and 5, are different Practice 1.
