When the instructions say to 「expand」, they mean that they’ve given me one log expression with lots of stuff inside it, and they want me to use the log rules to take the log apart into many separate log terms, each with only one thing inside its particular log.

Logarithm product rule The logarithm of a multiplication of x and y is the sum of logarithm of x and logarithm of y. log b (x ∙ y) = log b (x) + log b (y) For example: log b (3 ∙ 7) = log b (3) + log b (7) The product rule can be used for fast multiplication calculation using

Plots of logarithm functions of three commonly used bases. The special points log b b = 1 are indicated by dotted lines, and all curves intersect in log b 1 = 0. The graph of the logarithm to base 2 crosses the x-axis at x = 1 and passes through the points (2, 1), (4, 2), and

Ontario Log Rule The Ontario Log Rule is a method used in the forest industry to measure the volume of a log in board feet. It applies to logs with diameters from 4″ to 40″ (measured small end, inside bark) and lengths of the log from 8′ to 18′.

A logarithm is a function that does all this work for you. We define one type of logarithm (called “log base 2” and denoted \$\log_2\$) to be the solution to the problems I just asked. Log base 2 is defined so that \$\$\log_2 c = k\$\$ is the solution to the problem \$\$2^k

Summary: Natural Log Rules The natural log, or ln, is the inverse of e. The rules of natural logs may seem counterintuitive at first, but once you learn them they’re quite simple to remember and apply to practice problems. The four main ln rules are: ln(x)( y) = ln(x

Doyle Log Rule The Doyle Log Rule, developed around 1825, is based on a mathematical formula and is widely used throughout the southern United States. This rule allows for a saw kerf of 5/16 inch and a slabbing allowance of 4 inches, which is about twice

Estimate the board foot volume of a log using the Brereton Log Rule. The Brereton log rule does not take into account any deductions needed for saw kerf, slabs, or edgings and it gives the volume of a log in terms of board feet calculated at one cubic foot = 12 board

The function we have is log(logx) y = log(logx) We make use of chain rule Take u= logx du / dx =1/x Thus y= logu Differentiate the above equation wrt x, dy/dx = 1/u

Logarithms Formulas 1. if n and a are positive real numbers, and a is not equal to 1, then If a x = n, then log a n = x 2. log a n is called logarithmic function. The domain of logarithmic function is positive real numbers and the range is all real numbers. 3. log of 1 to

REMARK Notice the use of absolute value in the Log Rule. For those special cases in which u or x is restricted to positive values, we can omit the absolute value sign. For instance, in a problem in which u is known to be positive, you could write ∫

As a consequence, log b (x) diverges to infinity (gets bigger than any given number) if x grows to infinity, provided that b is greater than one. In that case, log b (x) is an increasing function. For b < 1, log b (x) tends to minus infinity instead. When x log b x goes to

In the first term, though, there’s still more than just one thing inside the log. In particular, I see that there’s an exponent inside the log. However, I can’t take the exponent out front yet, because that power is only on the x, not the 8. I have to remember that the rule
