9-62.

Without using a calculator, write the solution to each equation.

1. $2^{x} = 17$

Remember how to change the base using logarithms.

$\frac{\operatorname{log}17}{\operatorname{log}2}$

1. $\operatorname{log}_{3}\left(x + 1\right) = 5$

$242$

1. $\operatorname{log}_{3}\left(3^{x}\right) = 4$

$4$

1. $4^{\operatorname{log}}_{4}\left(x\right) = 7$

$7$
