3 Ways to Solve Logarithms - wikiHow

WebWhen we have an equation with a base e on either side, we can use the natural logarithm to solve it. How To Given an equation of the form y = Aekt, solve for t. Divide both sides of the equation by A. Apply the natural logarithm of both sides of the equation. Divide both sides of the equation by k. Example 6 Solve an Equation of the Form y = Aekt WebSolve log2(8) = x. I can solve this by converting the logarithmic statement into its equivalent exponential form, using The Relationship: log 2 (8) = x 2 x = 8 But 8 = 23, so I can equate powers of two: 2 x = 2 3 x = 3 Note that this could also have been solved by working directly from the definition of a logarithm.
