# Solving Log Equations Without Calculator

**If not, stop and use the steps for solving logarithmic equations containing terms without logarithms.**

**Solving log equations without calculator**.
Included is a discussion of the natural (ln(x)) and common logarithm (log(x)) as well as the change of base formula.
Here is how to calculate logarithms by hand using only multiplication and subtraction.
In this section we will discuss logarithm functions, evaluation of logarithms and their properties.

Determine if the problem contains only logarithms. Solving log equations there are two basic forms for solving logarithmic equations: Key steps in solving exponential equations without logarithms.

There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring (direct factoring, grouping, ac method), completing the square, graphing and others. Solving exponential equations with logarithms. Study each case carefully before you start looking at the worked examples below.

Note that the base in both the exponential form of the equation and the logarithmic form of the equation is b, but that the x and y switch sides when you switch between the two equations.if you can remember this — that whatever had been the argument of the log becomes the equals and whatever had been the equals becomes the exponent in the exponential, and vice versa — then you should. You can learn more about how the logarithmic function works by seeing the properties of its graph and studying the basic log rules. Logarithms and negative logs without a calculator

Make the base on both sides of the equation the same. Indeed, eliminating the logarithm is the easy part of solving log equations. Solving logarithmic equations generally, there are two types of logarithmic equations.

Logarithm considers being the fundamental concepts in mathematics. Before we can get into solving logarithmic equations, let’s first familiarize ourselves with the following rules of logarithms: As a result, before solving equations that contain logs, you need to be familiar with the following four types of log equations:
