Log Calculator

Log (Logarithm) calculator is used to calculate logarithm logbx where "b" is the base and "x" is a number. The logarithm of a number x for base b is the elevated exponent b to yield x.

What is a logarithm?

A logarithm is a mathematical operation that determines the power to which a number, called the base, must be raised to produce a given number. It essentially reverses the process of exponentiation.

More formally, if by = x, then the logarithm base b of x is y. This relationship is represented as:
logb (x) = y

Where:

  • ⁡log denotes the logarithm.
  • b is the base.
  • x is the number you're taking the logarithm of.
  • y is the exponent to which 
  • b must be raised to get x

Log base 10

Log10 calculator is a log equation solver used to calculate a log base 10 of the x number, generally lg(x) or log10(x). Log10 calculator is also known as decadic logarithm or common logarithm.

The typical logarithm of x is the power to be increased to be 10 for a value of x. Such as common logarithm of 10 is 1 and for 100 it is 2.

Log10(x)

In which 10 is raised to such a number to get the desired value of x

Log Base 2

This log equation calculator is used to measure the log base 2 of a number x which is usually written as lb(x) or log2(x).

Log2(x)

To get the value of x

Another term binary logarithm is also used for log base 2 calculator. To obtain the value x, the binary logarithm of x is the force to which the number 2 must be lifted.

For example logarithm of 1 will be 0, the binary logarithm of 8 is 3 and the binary logarithm of 4 is 2. It is often used in the philosophy of computer science and knowledge.

How to calculate a log?

Example 1:

What is log5 (3125) =?

The question is how many 5 there will need to be multiplied by each other to get 3125.

Solution:

5x5x5x5x5=3125

Hence we came to when five 5s are multiplied by each other we get the value 3125.

Log5 (3125) = 5

Example 2

Log (1000) =?

What will be the power of base 10 so the answer will be 1000?

Solution:

Log (1000) = 3

Because 103 =1000

Example 3

Log2 8 =?

So what will be the power of 2 to get the value of x = 8?

Solution:

As 2x2x2 = 8

So
Log2 8 = 3
