## Can log give negative values?

1. You can’t take the logarithm of a negative number or of zero. 2. The logarithm of a positive number may be negative or zero.

## Can a logarithmic equation have a negative solution?

Logarithms cannot have non-positive arguments (that is, arguments which are negative or zero), but **Quadratics and other equations can have negative solutions**. When we convert a log equation to a different type of equation by equating the insides of the logs, we may be “creating” solutions that didn’t previously exist.

## Can you take negative out of log?

Logarithms cannot have non-positive arguments (that is, arguments which are negative or zero), but **Quadratics and other equations can have negative solutions**. When we convert a log equation to a different type of equation by equating the insides of the logs, we may be “creating” solutions that didn’t previously exist.

## How do negative logs work?

Log (1/a) = -log a means that **The logarithm of 1 divided by some number is equal to the negative logarithm of that number**. (This is the exactly the opposite of the rule governing exponents where a number raised to a negative number is equal to 1 divided by that number raised to that power.)

## How do you solve a log with a negative value?

A common technique for handling negative values is to **Add a constant value to the data prior to applying the log transform**. The transformation is therefore log(Y+a) where a is the constant. Some people like to choose a so that min(Y+a) is a very small positive number (like 0.001). Others choose a so that min(Y+a) = 1.

## What does a negative log mean?

A negative logarithm means how many times to divide by the number. We can have just one divide: Example: What is log_{8}(0.125) … ? Well, 1 ÷ 8 = 0.125, So log_{8}(0.125) = −1.

## What are the 3 types of logarithms?

This information helps others identify where you have difficulties and helps them write answers appropriate to your experience level. Closed 6 years ago. In complex analysis I came across three types of logarithms namely **Ln, log and Log**.

## What is negative log on calculator?

Negative logarithm: It means the number of times we divide 1 by the base to achieve the log value. The negative of log_{Y} (x) is _{Y}Log (1 / x).

## What is 1 as a log?

The logarithm of 1 always equals **0**. Any number can serve as b, the base.

## Is log a real number?

Hence **Logarithm is defined only positive real numbers**. From the definition it is clear that the logarithm of a number has no meaning if the base is not mentioned. 2. The above examples shows that the logarithm of a (positive) real number may be negative, zero or positive.

## What are the 3 properties of logarithms?

**Logarithm Base Properties**

- Product rule: a
^{M}. a^{N}=a.^{M}^{+}^{N} - Quotient rule: a
^{M}/a^{N}= a.^{M-n} - Power of a Power: (a
^{M})^{N}= a.^{Mn}

## What are the properties of logs?

The properties of log are **Used to expand a single logarithm into multiple logarithms (or) compress multiple logarithms into a single logarithm**. A logarithm is just another way of writing exponents. Thus, the properties of logarithms are derived from the properties of exponents.

## Is log and ln the same?

The difference between log and ln is that **Log is defined for base 10 and ln is denoted for base e**. For example, log of base 2 is represented as log_{2} And log of base e, i.e. log_{E} = ln (natural log).

## Does ln have to be positive?

The outside function is ln x, and we know that **To be in the domain of ln x, x must be a positive number**.
