Rational exponents and radicals
In middle school, students learned about integer powers—first positive and then also negative. In Algebra 2, we extend this concept to include rational powers. We will define how they work, and use them to rewrite exponential expressions in various ways.
This course contains 5 segments:
Rational exponents
Properties of exponents (rational exponents)
Evaluating exponents & radicals
Equivalent forms of exponential expressions
Learn how to manipulate exponential expressions in different ways. For example, rewrite 8^x as 2^(3x).
Solving exponential equations using properties of exponents
Learn how to solve advanced exponential equations by manipulating the expressions in the equations using the properties of exponents. For example, solve 2^(x+1)=8^x by rewriting 8^x as 2^(3x) and then equating x+1=3x.
