Solving exponential equations without log

WebExponential Equations. The first technique we will introduce for solving exponential equations involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, S, and T, where [latex]b>0,\text{ }b\ne 1[/latex], [latex]{b}^{S}={b}^{T}[/latex] if and only if S = T.. In other words, when an … Web9 years ago. 1st Isolate the base with the exponent by dividing both sides by 5 and you get: 10^x-31=16.32. 2nd log both sides. log 10 of 10^x-31=log 10 of 16.32. The log 10 and 10 …

WebThe equations with logarithms on both sides of the equal to sign take log M = log N, which is the same as M = N. The procedure of solving equations with logarithms on both sides of the equal sign. If the logarithms have are a common base, simplify the problem and then rewrite it without logarithms. Make the base on both sides of the equation the SAME so that if bM=bN\large{b^{\color{blue}M}} = {b^{\color{red}N}}bM=bN then M=N{\color{blue}M} = {\color{red}N}M=N 1.
