## Intermediate Algebra: Connecting Concepts through Application

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: $150(1.6298...)^{5}$ $= 150(11.5)$ $= 1725$
