• ## Who uses logarithms 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 are logarithms used for in math?

Logarithms are the inverse of exponents. A logarithm (or log) is the mathematical expression used to answer the question: How many times must one “base” number be multiplied by itself to get some other particular number? For instance, how many times must a base of 10 be multiplied by itself to get 1,000?

### What do logarithms do in real life?

The Real-Life scenario of Logarithms is to measure the acidic, basic or neutral of a substance that describes a chemical property in terms of pH value.

### 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.

Why do we study logarithms?

Why are we studying logarithms? As you just learned, logarithms reverse exponents. For this reason, they are very helpful for solving exponential equations.

## How are logarithms used in finance?

Using logs, or summarizing changes in terms of continuous compounding, has a number of advantages over looking at simple percent changes. For example, if your portfolio goes up by 50% (say from \$100 to \$150) and then declines by 50% (say from \$150 to \$75), you’re not back where you started.

## Why do students struggle with logarithms?

Students struggle greatly with both the concept of logarithms as inverse functions and the processes and procedures needed for working with logarithmic equations. Much of this difficulty stems from trouble students have interpreting notation used to express logarithms.

What grade do you learn logarithms?

Indeed, students don’t usually learn anything about logarithms until Algebra 2 or even Precalculus. One result of this is that calculus students always seem very comfortable with square roots, but have a very shaky knowledge of logarithms, even though the two concepts have about the same difficulty level.

### Why do economists use logarithms?

Linear functions are useful in economic models because a solution can easily be found. However non-linear functions can be transformed into linear functions with the use of logarithms. The resulting function is linear in the log of the variables.

### Are logarithms used in business?

The logarithmic function is applicable when modeling business applications. This is because it offers a constant mathematical relationship, constant constraints themes which are set by the administrator for every group of significant factors. Thus, the equation is controlled by the situational constraints.

What level of math is logarithms?

The usage of logarithm is considered arithmetic since it is manipulating number. And the laws of logarithms would be considered algebra.

## At what age do you learn logarithms?

Indeed, students don’t usually learn anything about logarithms until Algebra 2 or even Precalculus.

## Who invented logarithms?

John NapierLogarithm / Inventor
John Napier, the Scottish mathematician, published his discovery of logarithms in 1614. His purpose was to assist in the multiplication of quantities that were then called sines. The whole sine was the value of the side of a right angled triangle with a large hypotenuse, say 107 units long.

Are logarithms tough?

Logarithms is one material that is difficult for students [1]. Another study on the difficulties in learning logarithms said that students are more focused on the procedural approaches and depended too much on rules rather than the concept of logarithm itself[2].

### Are logarithms used in finance?

Logarithms are often a much more useful way to look at economic data. For example, here is a graph of an overall U.S. stock price index going back to 1871. Plotted on this scale, one can see nothing in the first century, whereas the most recent decade appears insanely volatile.

### Is log a calculus or algebra?

What level math is logarithms?
