## What happens if you take a log of a log?

Well, remember that logarithms are exponents, and when you multiply, you’re going to add the logarithms.

The log of a product is the sum of the logs..

## How are logarithms used in real life?

Exponential and logarithmic functions are no exception! 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 the Antilog?

An antilog is the result of raising the base being used to the logarithm given or calculated. Put another. way, it “undoes” what calculating the logarithm of a number does and simply returns that number. In an equation of the form logbx = y, it is the “x” term, called the argument of the log function.

## How do logarithms make our life easier?

Logarithmic transformations are also extremely useful for making it easier to see patterns in data. When logarithmic transformation straightens out a function, it becomes the exponential function–making it much easier to read and more understandable (Burrill et. al, 1999).

## How do you explain logarithms?

Logarithms or logs are a part of mathematics. They are related to exponential functions. A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Historically, they were useful in multiplying or dividing large numbers.

## Can the base of a log be negative?

While the value of a logarithm itself can be positive or negative, the base of the log function and the argument of the log function are a different story. … To understand why, we have to understand that logarithms are actually like exponents: the base of a logarithm is also the base of a power function.

## How do you solve log problems?

We use the following step by step procedure:Step 1: bring all the logs on the same side of the equation and everything else on the other side.Step 3: Exponentiate to cancel the log (run the hook).Step 4: Solve for x.Step 5: Check your answer.Step 1: Take logs of both sides using one of the given bases.More items…

## What is opposite of log?

Logarithms are the “opposite” of exponentials, just as subtraction is the opposite of addition and division is the opposite of multiplication. Logs “undo” exponentials.

## Is ln the opposite of log?

What is the inverse function of the natural logarithm of x? The natural logarithm function ln(x) is the inverse function of the exponential function ex.

## What is the meaning of log?

log noun [C] (RECORD) a full, written record of a trip, a period of time, or an event: a ship’s log.

## Can you cancel out logs on both sides?

If you have the same operation on both sides of an equation, they cancel each other out! Keep in mind that this only works when the logarithms on both sides of the equation have the same base. If you had a logarithm with base 3 on one side and a logarithm with base 7 on the other side, they won’t cancel out.

## What is the purpose of logarithms?

Logarithms are a convenient way to express large numbers. (The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division.

## How do you cancel out a log?

To rid an equation of logarithms, raise both sides to the same exponent as the base of the logarithms. In equations with mixed terms, collect all the logarithms on one side and simplify first.

## What happens when log goes to other side?

The base of the log is 10, so we must raise both sides of the equation to be powers of 10: … First, we’ll move the 4 to the other side to get the natural log by itself: The base of the log is e, so we must raise both sides of the equation to be powers of e: On the left hand side, the e and ln cancel, leaving just 3x.

## Are logarithms hard?

No. I’ve never understood why people think logarithms are hard; it’s very common for people to feel uncomfortable with them. Trigonometric functions are harder to deal with but people tend to be more comfortable with them than logarithms.

## What is the meaning of sleep like a log?

Sleep very soundly, as in I slept like a log, or She said she slept like a top. … Both of these similes transfer the immobility of an object to that of a person who is sound asleep (since a top spinning quickly looks immobile).

## How do you take the log?

Step 3: Use a common log table. Now, use row number 15 and check column number 2 and write the corresponding value. So the value obtained is 1818. Step 4: Use the logarithm table with a mean difference….Related LinksExponential FunctionLogarithm FormulaLog Base 2Logarithms
