WebUse logarithms to solve exponential equations. Sometimes the terms of an exponential equation cannot be rewritten with a common base. In these cases, we solve by taking the logarithm of each side. Recall, since. \mathrm {log}\left (a\right)=\mathrm {log}\left (b\right) log(a) = log(b) is equivalent to a = b, we may apply logarithms with the ... WebNov 24, 2024 · I am having trouble with the following problem, which is about solving exponential equations using logarithms with base 10: Initially, I thought I'd take the log of $2^x-1$ and $4^{2x+1}$ separately, and then multiply them. But that didn't work, because there's no rule for multiplying logs to combine them.
