This is why we teach students about logarithms today. For example, in order to integrate $\frac 1 x$ in calculus, you "need the logarithm". Of course, you could just numerically integrate it, but it's useful to know that the result of that integration is actully a function with certain algebraic properties and which turns up as the answer to ...

27 Αυγ 2020 · 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.
16 Μαΐ 2021 · There are 6 main reasons why we use the natural logarithm: The log difference is approximating percent change The log difference is independent of the direction of change
Logarithms are primarily used for two thing: i) Representation of large numbers. For example pH (the number of hydrogen atoms present) is too large (up to 10 digits). To allow easier representation of these numbers, logarithms are used. For example let's say the pH of the substance is 10000000000.
This lesson presents an introduction to logarithms. What they are, their relationship to exponents and some real-world applications of them. Emphasis is placed on why we need logarithms and how they are used in science.
A logarithm can have any positive value (other than 1) as its base, but logs with two particular bases are generally regarded as being more useful than the others: the "common" log with a base of 10, and the "natural" log with a base of the number e.
14 Μαΐ 2021 · Currently, in my math class, we are learning about logarithms. I understand that the common logarithm has a base of 10 and the natural has a base of e. But, when do we use them? For example the equation $7^{x-2} = 30$ in the lesson, you solve by rewriting the equation in logarithmic form $\log_7 30 = x-2$. The,n apply the change of base formula ...
