This tutorial reviews how to simplify exponential expressions containing exponents. Some examples show expressions that have like bases that are being multiplied and you have to add their exponents. Other examples show expressions with like bases that are being divided and you have to subtract their exponents. Also view examples when an exponent is being raised by another exponent such as (3x^2)^2, When an exponent is raised to a power, you will have to multiply the exponents.
