Chapter 5 - Exponential Functions - 5.2 Solving Equations Using Exponent Rules - 5.2 Exercises - Page 438: 89

1. Power equation 2. $r \approx 1.63$

1. Power equation For example: The variable is raised to the power of a number. 2. Solve $150r^{5} = 1725$ $r^{5} = 11.5$ $r = 11.5^{\frac{1}{5}} $ $r = 1.6298...$ $r \approx 1.63$ Check: $ 150(1.6298...)^{5} $ $= 150(11.5)$ $= 1725$
