Properties of Logarithms – Condensing Logarithms logarithms as a single logarithm is often required when solving logarithmic equations. The 5 propertie s used for condensing logarithms are the same 5 properties used for expanding logarithms.

Introduction to Logarithms - Math is Fun Sometimes a logarithm is written without a base, like this: log(100) This usually means that the base is really 10. It is called a 'common logarithm'. Engineers love to use it. On a calculator it is the 'log' button. It is how many times we need to use 10 in a multiplication, to get our desired number.

Solving Logarithmic Equations - ChiliMath If you see “log” without an explicit or written base, it is assumed to have a base of 10. In fact, logarithm with base 10 is known as the common logarithm. What we need is to condense or compress both sides of the equation into a single log expression. On the left side, we see a difference of logs which means we apply the Quotient Rule while the right side requires Product Rule because they’re the sum of logs.

Laws of Logarithms - Windstream Writing logs as single logs can be helpful in solving many log equations. 1) Log 2 (x + 1) + Log 2 3 = 4 Solution: First combine the logs as a single log. Log 2 3(x + 1) = 4 Now rewrite as an exponential equation. 3(x + 1) = 2 4 Now solve for x.
