Introduction to Log Calculator

Logarithm contributes in advance science and astronomy as it helps in surveying, celestial navigation and other domains. Pierre Simon Laplace called logarithm. Log calculator is an online tool from which you can take logarithm of any value easily. Logarithm calculator offers a digital way of calculating over manual calculations.

The first such table was compiled by Henry Briggs in 1617, after Napier's Invention. Find complete tutorial of logarithm to learn its formulas, equations and calculations performed by logarithm calculator.

What is Logarithm?

The logarithm is the inverse of the exponent function. By inverse, it means a function that does the opposite of the exponent function.

Consider an examples like subtraction is the inverse of addition and division is the inverse of multiplication. Where exponent means to multiply a number "x" times like 2x and multiply them together. Product rule of logarithms calculator with its fast calculations makes it easy for you to work quickly.

Log Function of Logarithm Calculator

Logarithm identify the ways to repeatedly multiply the base for getting number. Log properties calculator uses the log functions to compute results. For example, log2 (x) counts how many 2s would need to be multiplied to make x.

24 = 16

Log2 (16) = 4

Both deals with this series of multiplication 2x2x2x2

The exponent takes the count and multiplies to make a number. Logarithms take the final number and determine the count of multiplication. The log function is all about repetition of numbers and using logarithmic calculator makes it easy to understand this concept.

After getting the logarithm of actual number you can use sigfig converter for calculating answer in precise form.

Common Factors in Exponents and Logarithms

Exponents and logarithms deal with the "base". The "base" of the exponent is same as the base of the logarithm. Product rule of logarithms calculator calculates this also while computing. Base is vertically the lowest number to write in both cases.

Such as 4x and log4 (x) are both base 4 and these bases are directly connected

If 4x = y then log4 (y) = x

In order to avoid the problems you can find the numerical value of the log expression calculator as it deals with different things efficiently.

Logarithm Rules used by Log Calculator

Product rule of logarithms calculator uses logarithm rules to get results. Logarithm rules determines the relationship between natural log and exponential function.

S eln c = c ...... 1

By combining the values of "c", we get

Ln (ek) = k ..... 2

These equations explains that ex and lnx are inverse functions. Let's drive the rules of logarithms based on equation.

Rule #1: Product Rule

ln (xy) = ln(x)+ln(y)

Product rule makes it easy for the product rule of logarithms calculator to calculate the sum of the log of its factors.

Rule #2: Quotient Rule

ln (x/y) = ln(x)−ln(y)

With using quotient rule, the log properties calculator can identify whether the quotient is equal to the difference of log.

Rule #3: Log of Power

ln (xy) = yln(x)

By using the log of power, the properties of logarithms calculator makes sure that the product of number and logs are written as power.

Rule #4: Log of e

ln (e) = 1

Rule #5: Log of One

ln (1) = 0

Rule #6: Log of Reciprocal

ln (1/x) = − ln(x)

Logarithm calculator uses log of reciprocal to substitute the value to the log of power rule.

Applications of Logarithms

Logarithm applications can be found inside and outside the mathematics. The logarithms are used in

  • Logarithmic Scale
  • Fractals
  • 2 Digit Expense Calculation
  • Finding Order of Magnitude
  • Calculating Interest Rates
  • Logarithmic Graphs

Since there are a lot of applications of the logarithm, using an logarithmic properties calculator becomes handy to save time and increase efficiency.
