11.4 Properties of Logarithms
a. The first thing we must do is move the coefficients from the front into the exponents by using property 3. This gives us. 4 ln 2 + 2 ln x – ln y = ln 24
Logarithms
The natural logarithm is a logarithm with a specific base: e ≈ 2.71828. This number is called the Euler's number. loge x = ln x. All the properties of the

(2nd half of text) Section 4.4, Logarithmic FunctionsDefinition of General Logarithmic Function:
A logarithmic function, denoted by
logbyx , is equivalent to ybx In previous algebra classes, you may have often used the number 10 as a base for a logarithmic function. These were called common logarithms. In calculus, the most useful base for logarithms is the number e. These are called natural logarithms.Definition of the Natural Logarithmic Function:
The natural logarithmic function is denoted by
lnyx , which is equivalent to saying logeyx . The function lnyx is true if and only if yex . The natural logarithmic function is the inverse of the natural exponential function. The Natural Logarithmic function can be written in logarithmic form or exponential form.Examine the comparison below.
