Answer
$0.91$
Work Step by Step
The base in the exponential equation is 10, so take the common logarithm on both sides to obtain
$\log{10^x}=\log{8.07}.$
Use the inverse property $\log{10^x}=x$ on the left side of the equation to obtain
$x=\log{8.07}.$
Use a calculator and round-off the answer to two decimal places to obtain
$x \approx 0.91.$
