7-4: Rational Exponents • Another way to write a radical expression is to use a radical exponent. • Examples:
7-4: Rational Exponents • Rational Exponents can be simplified just like their radical counterparts. • Examples:
7-4: Rational Exponents • Your turn • Simplify Note that: 1) Like variables, you can add exponents when the base is the same 2) You can multiply bases when the exponent is the same
7-4: Rational Exponents • A rational exponent may have a numerator other than 1. The property (am)n = amn shows how to rewrite such an expression. or • Basically, the numerator is the powera number is being raised to. The denominator is the roota number is being taken to.
7-4: Rational Exponents • We can convert between the two forms • Write the exponential expression in radical form: • Write the radical expressions in exponential form:
7-4: Rational Exponents • Your Turn • Write the exponential expression in radical form: • Write the radical expressions in exponential form:
7-4: Rational Exponents • Simplifying Numbers with Radical Exponents • All the properties of integer exponents also apply to rational exponents. • See page 381 in your books for a summary. • Examples:
