8-127.

Use properties of logs to solve each of the following equations. Use exact values. Homework Help ✎

log(

*x*+ 3) = 2ln(

*x*+ 3) = 2ln 3 + ln(

*x*) = 4ln(

*x*+ 4) − ln(*x*) = 2

10^{log(}^{x}^{+3)} = 10^{2}*x* + 3 = 100*x* = 97

*e*^{log(}^{x}^{+3)} = *e*^{2}

ln(3*x*) = 4*e*^{ln(3}^{x}^{)} = *e*^{4}

*x* + 4 = *xe*^{2}*x* − *xe*^{2} = −4*x*(1 − *e*^{2}) = −4
