Question
Solve each exponential equation. Express the solution set in terms of natural logarithms or common logarithms. Then use a calculator to obtain a decimal approximation, correct to two decimal places, for the solution.$$10^{x}=3.91$$$$19^{x}=143$$
Step 1
For the first equation, we get: $$\ln(10^{x})=\ln(3.91)$$ For the second equation, we get: $$\ln(19^{x})=\ln(143)$$ Show more…
