WebbBy establishing the relationship between exponential and logarithmic functions, we can now solve basic logarithmic and exponential equations by rewriting. Example 4.2.3. Solve log 4 ( x) = 2 for x. By rewriting this expression as an exponential, 4 2 = x , so x = 16. Most calculators and computers will only evaluate logarithms of two bases. WebbProperties of Logarithms. Let M and N arbitrary positive number such that a > 0, a ≠ 1, b > 0, b ≠ 1 then. log a MN = log a M + log a N. log a M N = log a M – log a N. log a N α = α log a N (α any real no;) log aβ N α = α β log a N (α ≠ 0, β ≠ 0) log a N = log b. ⁡. N log b. WebbSolving Logarithmic Equations Remember that logaM =x means exactly the same thing as ax = M , that is, "logaM is the number to which you raise a in order to get M." This is the key to solving equations in which logarithms appear. For example: Suppose we want to solve the equation log2 y = 3. new creation women\u0027s clinic
