Solve for b, x or y in the logarithm equation $$\log_{b}x = y$$

Calculate the percent change from one value to another, from V1 to V2, or

$$\text{Percentage Change} = \dfrac{\Delta V}{|V_1|} \times 100$$

Calculate the percent increase from a starting value to a final value, or

$$\text{Percentage Increase} = \\ \dfrac{\text{Final Value} - \text{Starting Value}}{\left|\text{Starting Value}\right|} \times 100$$

Calculate the percent decrease from a starting value to a final value, or

$$\text{Percentage Decrease} = \\ \dfrac{\text{Starting Value} - \text{Final Value}}{\left|\text{Starting Value}\right|} \times 100$$

Calculate the percent difference for two values, V1 and V2, or

$$\text{Percentage Difference} = \dfrac{|\Delta V|}{\left[\dfrac{\Sigma V}{2}\right]} \times 100$$

Calculate the percent error of the Experimental (measured) value to the Theoretical (actual) value, or

$$\text{Percentage Error} = \dfrac{| E-T |}{| T |}\times100$$
