Answer
Fill the blank with: x.
Fill the table with values
$3, 2, 1, 0, -1,-2,-3,1/2$
Work Step by Step
By definition, $\log_{a}x=y \Leftrightarrow a^{y}=x$
($\log_{a}x$ is the exponent to which the base $a$ must be raised to give $x$.)
If the base is 10, then $\log x=y \Leftrightarrow 10^{y}=x$
$\log 10^{3}=3, \log 10^{2}=2, $etc.
The table is filled with:
$3, 2, 1, 0, -1,-2,-3,1/2$
