Webpower-law distribution. Such graphical analysis can be erroneous, especially for data plotted on a log-log scale. In this scale, a pure power law distribution appears as a straight line in the plot with a constant slope. The pure power-law distribution, known as the zeta distribution, or discrete Pareto distribution [6] is expressed as: 1 () WebDefine the quotient and power rules for logarithms. Use the quotient and power rules for logarithms to simplify logarithmic expressions. For quotients, we have a similar rule for logarithms. Recall that we use the quotient rule of exponents to combine the quotient of exponents by subtracting: {x}^ {\frac {a} {b}}= {x}^ {a-b} xba = xa−b.
