What do we use logarithms for in real life?

Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).

What is logarithm and why do we need it?

Logarithms are defined as the solutions to exponential equations and so are practically useful in any situation where one needs to solve such equations (such as finding how long it will take for a population to double or for a bank balance to reach a given value with compound interest).

What exactly is logarithm?

A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number.

How do engineers use logarithms?

All types of engineers use natural and common logarithms. Chemical engineers use them to measure radioactive decay, and pH solutions, which are measured on a logarithmic scale. Exponential equations and logarithms are used to measure earthquakes and to predict how fast your bank account might grow.

How are logarithms used in science?

Logarithms have many uses in science. pH — the measure of how acidic or basic a solution is — is logarithmic. So is the Richter scale for measuring earthquake strength. In 2020, the term logarithmic became best known to the public for its use in describing the spread of the new pandemic coronavirus (SARS-CoV-2).

How are logarithms used in medicine?

How do Doctors Use Logarithms? Logarithms are used by Physicians in both nuclear and internal medicine. For example, they are used for investigating pH concentrations, determining amounts of radioactive decay, as well as amounts of bacterial growth. Logarithms also are used in obstetrics.

Are logarithms hard?

Logarithms is one material that is difficult for students [1]. Other study revealed that students often see log notations as an object, not an operation[3]. Therefore, students often do cancelation on a logarithmic form. For example, ln (7x – 12) = 2 ln x, becomes(7x – 12) = 2x.
