Simplifying Expressions with Exponents - Problem 5 139 views
When you multiply two fractions that involve exponential expressions, if there are any powers raised to powers, you should simplify those first. Use the power to power rule where the exponents are multiplied. From there, you can either reduce each fraction first and then multiply, or you can multiply first and reduce later. You should get the same result either way. Remember to multiply the coefficients, but add the exponents.
