How to solve for x using logs
WebExample 2: Compress the following expression as a single logarithm by using logarithmic formulas. 5 log x + log y - 8 log z. Solution: To find: The compressed form of the given expression as a single logarithm using logarithm formulas. 5 log x + log y - 8 log z = (5 log x - 8 log z) + log y (Regrouped the terms) = (log x 5 - log z 8) + log y ... WebMay 25, 2024 · To solve for x, we use the division property of exponents to rewrite the right side so that both sides have the common base, 3. Then we apply the one-to-one property of exponents by setting the exponents equal to one another and solving for x:
