#4 Solving Expo & Log Equations

Find the exact value of the logarithm without using a calculator.

 $\log_{\sqrt{5}}25$  

(a)  

Solve the logarithmic equation.

 $\log_7343=2x+1$  

x = (a)  

Solve the logarithmic equation.

 $\log_6\sqrt{x-2}=2$  

x = (a)  

Choose the correctly expanded natural logarithm:

 $\ln\left(\frac{7a}{bc}\right)\$  

•  $\ln7+\ln a-\ln b-\ln c$  

•  $\ln7+\ln a-\ln b+\ln c$  

•  $\ln(7a)-\ln(bc)$  

•  $7\ln a-b\ln c$  

Choose the correctly condensed common logarithm

 $\log q+\log r+3\log s$  

•  $\log\left(qrs^3\right)$  

•  $\log\left(qrs\right)^3\ \ \ \$  

•  $\log\left(3qrs\right)\ \ \ \ \$  

•  $3\log\left(qrs\right)$
