WebMar 10, 2024 · 3. Apply the quotient rule. If there are two logarithms in the equation and one must be subtracted by the other, you can and should use the quotient rule to combine the two logarithms into one. Example: log 3 (x + 6) - log 3 (x - 2) = 2. log 3 [ (x + 6) / (x - 2)] = 2. 4. Rewrite the equation in exponential form. WebTo solve for x x, we must first isolate the exponential part. To do this, divide both sides by 5 5 as shown below. We do not multiply the 5 5 and the 2 2 as this goes against the order of …
