Using exponents to solve problems

Using exponents to solve problems

In this section, you will try to apply what we learn about exponents in the previous sections to solve word problems such as, calculating the volume of a cube, and more.
Basic Concepts: Using exponents to describe numbers, Exponent rules, Order of operations with exponents
Related Concepts: Combining the exponent rules, Convert between radicals and rational exponents, Solving for exponents
