Simplifying Radicals Medina2 Rule 1: There are NO perfect squares underneath the radical symbol. There are NO fractions underneath the radical symbol. Rule 2: Rule 3: There are NO radicals in the denominator. Rule 4: There are NO negatives underneath a square root.

3
Simplifying Radicals 1 st Method : Ask yourself, what are the factors of 8? Think of biggest perfect square that’s a factor of 8: 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225,..., 625 Any number(s) that does not have a square root stays in the radical.

4
Simplifying Radicals 1 st Method : Ask yourself, what are the factors of 18? Think of biggest perfect square that’s a factor of 18: 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225,..., 625 Or when in doubt, prime factor out.
