Web To solve for y, first take the log of both sides: log 5 = log 3 y. By the identity log x y = y · log x we get: log 5 = y ⋅ log 3. Dividing both sides by log 3: y = log 5 log 3. Using a calculator we can find that log 5 ≈ 0.69897 and log … From calculatorsoup.com
Since we want to transform the left side into a single logarithmic equation, we should use the Product Rule in reverse to condense it.
Start by condensing the log expressions on the left into a single logarithm using the Product Rule. We want to have a single log expression on each side of the equation.
This is an interesting problem. What we have here are differences of logarithmic expressions on both sides of the equation.
If you see “log” without an explicit or written base, it is assumed to have a base of 10. In fact, a logarithm with base 10 is known as the common logarithm.
This problem involves the use of the symbol \ln instead of \log to mean logarithm. Think of \ln as a special kind of logarithm using base e where e \approx 2.71828.
