Note: Yes, you can use this method all of the time! While changing the bases to be the same to rewrite the question can be easier sometimes, taking the log of both sides will always solve exponential equations.

Solve the exponential equation below.

$\sage {base5}^{\sage {factor5a}} = \sage {base5}^{\sage {factor5b}}$

$x = \answer [tolerance=0.05]{\sage {solution5}}$

Solve the exponential equation below.

$\sage {base6a}^{\sage {factor6a}} = \sage {base6b}^{\sage {factor6b}}$

$x = \answer [tolerance=0.05]{\sage {solution6}}$

Solve the exponential equation below.

$\left (\sage {base7a}\right )^{\sage {factor7a}} = \sage {base7b}^{\sage {factor7b}}$

$x = \answer [tolerance=0.05]{\sage {solution7}}$

Solve the exponential equation below.

$\sage {base8a}^{\sage {factor8a}} = \sage {base8b}^{\sage {factor8b}}$

$x = \answer [tolerance=0.05]{\sage {solution8}}$

Solve the exponential equation below.

$\sage {base9a}^{\sage {factor9a}} = \sage {base9b}^{\sage {factor9b}}$

$x = \answer [tolerance=0.05]{\sage {solution9}}$

Solve the exponential equation below.

$\sage {base10a}^{\sage {factor10a}} = \sage {base10b}^{\sage {factor10b}}$

$x = \answer [tolerance=0.05]{\sage {solution10}}$

Solve the exponential equation below.

$\sage {base11a}^{\sage {factor11a}} = \sage {base11b}^{\sage {factor11b}}$

$x = \answer [tolerance=0.05]{\sage {solution11}}$

Main takeaway: Before looking, you should work through the previous problems. Have you finished working through the examples? $\answer [format=string]{Yes}$

While changing the bases to be the same to rewrite the question can be easier sometimes, taking the log of both sides will always solve exponential equations.
