How do you evaluate logarithmic expressions

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. WebExample 1: Evaluate the expression below using Log Rules. {\log _2}8 + {\log _2}4 log28 + log24 Express 8 8 and 4 4 as exponential numbers with a base of 2 2. Then, apply Power Rule followed by Identity Rule. After doing so, you add the resulting values to get your final answer. So the answer is \color {blue}5 5.
