Radical Expressions CA 2.0

Objective - To simplify radical expressions.

Parts of a Radical

Rules for Simplifying Radicals No perfect square factor in a radical. No fractions or decimals in a radical. No radicals in a denominator.

1) No perfect square factor in a radical.

2) No fractions or decimals in a radical.

3) No radicals in a denominator. (aka RATIONALIZE the denominator)

CONJUGATES Conjugates are almost like opposites, but instead of changing both signs, only the middle sign changes.

State the conjugate of the radical expression.
