Solve each equation. Give exact solutions. $$ \log (6 x+1)=\log 3 $$
To four decimal places, the values of \(\log _{10} 2\) and \(\log _{10} 9\) are $$\log _{10} 2=0.3010 \text { and } \log _{10} 9=0.9542$$ Use these values and the properties of logarithms to evaluate each expression. DO NOT USE A CALCULATOR. See Example 5. $$ \log _{10} 9^{5} $$
Solve each equation. Approximate solutions to three decimal places. $$ 9^{-x+2}=13 $$
Determine whether common logarithms or natural logarithms would be a better choice to use for solving each equation. Do not actually solve. $$ 10^{3 x+1}=13 $$
Determine whether common logarithms or natural logarithms would be a better choice to use for solving each equation. Do not actually solve. $$ e^{-0.28 x}=30 $$
