Use the product property of logarithms to write the logarithm as a sum of logarithms. Then simplify if possible. Assume that all variable expressions represent positive real numbers. \[ \log (17 p q)=\square \] $\square \circ \square$

Step 1 ：Given the logarithmic expression \(\log (17 p q)\).

Step 2 ：The product property of logarithms states that the logarithm of a product is the sum of the logarithms of its factors. Therefore, we can apply this property to the given logarithm to write it as a sum of logarithms.

Step 3 ：So, \(\log (17 p q)\) can be written as \(\log (17)+\log (p)+\log (q)\).

Step 4 ：Therefore, the final simplified form of the given logarithmic expression is \(\boxed{\log (17)+\log (p)+\log (q)}\).
