: This is a question where we have to prove that log x + 2 log y-3 = log (xy^2/1000).how can we prove that?
working on the left side fo the equation:
1. rewrite 3 as log 1000,
2. use the three properties of logarithms (sum, difference, and power) that are in practically every algebra text under the sections containing logarithms.
