7-52.

Solve each of the following equations. Homework Help ✎

1. $5e^x=30$

$e^x=6$

$x\ln(e)=\ln(6)$

1. $200(1.05)^x=5000$

Divide both sides by $200$ before taking the log of both sides and bringing the '$x$' down.

1. $\log_3(x+5)=4$

Rewrite the equation in exponential form.

1. $5\ln(x)-7=18$

$5\ln(x)=25$

$\ln(x)=5$

Rewrite the equation in exponential form.
