How do you solve an exponential equation

WebHere is how to solve exponential equations: Manage the equation using the rule of exponents and some handy theorems in algebra. Use the theorem above that we just proved. Solve \displaystyle { \frac {1} {5^ {x-1}} = 125} . 5x−11 = 125. Making the bases on both sides equal to 5 gives 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.
