Chapter 4 - Exponential and Logarithmic Functions - Exercise Set 4.2 - Page 465: 7



Work Step by Step

From the definition of the logarithmic function on page 456, we know that $y=log_b{x}$ is equivalent to $b^{y}=x$ (for $x\gt0$, $b\gt0$, and $b\ne1$). Therefore, $y=log_6{216}$ is equivalent to $6^{y}=216$ in exponential form.
