Essential Question Essential Vocabulary How do we simplify expressions containing radicals? Essential Vocabulary Radical expression Exponent Rationalize

Simplifying Radical Expressions Terminology: radical, principle root, index of radical, radicand Simplify by dividing index into exponents of variables Examples…

Rationalizing Expressions What does it mean to rationalize the denominator of an expression? Rationalizing the denominator means removing the radical from the denominator. Calculus requires us to also rationalize the numerator. Examples…
