Answer
$x \approx 2.40$
Work Step by Step
Divide $9$ on both sides of the equation to obtain:
$e^x=11$
RECALL:
$\ln{e^x}=x$
Take the natural logarithm of both sides to obtain:
$\ln{e^x}=\ln{11}$
Use the rule above to obtain:
$x=\ln{11}$
Use a scientific calculator to obtain:
$x=2.397895273
\\x \approx 2.40$
