Logarithms Calculator: Finding Logarithms is not a difficulty anymore. As we have provided with the logarithm calculator that gives you the output immediately by giving some inputs. Along with this calculator we have also provided with the steps and examples on how to calculate the logs manually.

How to Calculate Logorithms Manually?

Logorithm is nothing but inverse of exponents. Logarithm is the power to which the number is raised in order to get some other numbers. Formula of logorithm is,

bx = y ⇒ logby = x

where,

b is the base,

x is the exponent.

a,b,x are positive real numbers.

Take a look at these steps that are given below to calculate the logarithm of a number easily.

  • Give the equation that was given in the problem.
  • Then, use the formula that was given above.
  • Finally, after simplifying you will get the value of log.

Example:

Question: Find the logarithm value of log24?

Solution:

Given value, log24

logby = x ⇒bx = y

log24 = x

2x  = 4

x =2.

Therefore, the value of x in  log24 is 2.
