## Where is Log used in physics?

In simple cases the logarithm counts factors in multiplication. It is used in physics to make bigger calculations easy without using calculator. Log is a part calculus.

### What does the log function do?

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Why are logarithms used?

Logarithms are the inverse of exponents. A logarithm (or log) is the mathematical expression used to answer the question: How many times must one “base” number be multiplied by itself to get some other particular number?

Why do we use logarithms in physics?

Logarithms of the latter sort (that is, logarithms with base 10) are called common, or Briggsian, logarithms and are written simply log n. Invented in the 17th century to speed up calculations, logarithms vastly reduced the time required for multiplying numbers with many digits.

## What are common logarithms with solutions?

Logarithms to the base 10 are called common logarithms (Brigg’s logarithms). x = log ⁡ c b + log ⁡ b c, y = log ⁡ a c + log ⁡ c a, z = log ⁡ a b + log ⁡ b a, t h e n x 2 + y 2 + z 2 − 4 = x y z. a, then x2 + y2 + z2 − 4 = xyz. Logarithm examples with solutions are given below.

### What is the base of ∴ log?

‘log’ is the abbreviation of the word ‘logarithm’. Common logarithm (Brigg’s logarithms). The base is 10. = 1, then log a x is an imaginary. ∴ log is not defined. ∴ log is not defined.

What is an example of a monotonically increasing and decreasing log?

If a > 1, then a x is monotonically increasing. For example, If 0 < a < 1, then a x is monotonically decreasing. For example, ‘log’ is the abbreviation of the word ‘logarithm’. Common logarithm (Brigg’s logarithms). The base is 10. = 1, then log a x is an imaginary.

What is the characteristic and mantissa of log 564?

The integral part of a logarithm is called the characteristic and the fractional part (decimal part) is called mantissa. ⇒ The mantissa of the log of a number is always kept positive. i.e., if log564 = 2.751279, then 2 is the characteristic and 0.751279 is the mantissa of the given number 564.
