How to solve logarithms by hand

WebThe logs of negative numbers (and you really need to do these with the natural log, it is more difficult to use any other base) follows this pattern. Let k > 0 ln (−k) = ln (k) + π 𝑖 For other bases the pattern is: logₐ (−k) = logₐ (k) + logₐ (e)*π 𝑖 … 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
