Witryna27 sie 2024 · Definition A logarithm is the answer to the question what power x do I need to apply to the base b in order to obtain the number y: log_b (y) = x is another way of specifying the relationship: b^x = y Let’s plug in some numbers to make this more clear. We will do base-10, so b=10. Witryna30 sty 2024 · The pH scale is logarithmic, meaning that an increase or decrease of an integer value changes the concentration by a tenfold. For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10.

WitrynaA logarithm answers the question "How many of this number do we multiply to get that number?" Example How many 2s must we multiply to get 8? Answer: 2 × 2 × 2 = 8, so we had to multiply 3 of the 2s to get 8. We say the logarithm of 8 with base 2 is 3. In fact these two things are the same: Introduction to Logarithms. Witryna13 lut 2024 · Definition 10.4.1: Logarithmic Function The function f(x) = logax is the logarithmic function with base a, where a > 0, x > 0, and a ≠ 1. y = logax is equivalent to x = ay Convert Between Exponential and Logarithmic Form Since the equations y = logax and x = ay are equivalent, we can go back and forth between them. central medical record technician salary
