Answer
$\approx 0.1803$
Thus , both the equations are same.
Work Step by Step
Apply logarithmic property : $\log m+ \log n=\log (mn)$
We will write the equation in the form of the logarithmic expression and evaluate the result.
$\log_{10} (\dfrac{518}{342})=\log_{10} 518-\log_{10} 342 \approx 0.1803$
Thus , both the equations are same.
