    Logarithm

    In mathematics, the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication. For exa…

    Work? Logarithms “The Logarithm of a given number to a given base is the index of the power to which the base must be raised in order to equal the given number.” If a > 0 and ≠ 1 then logarithm of a positive number N is defined as the index x of that power of ‘a’ which equals N i.e.,

    What are Logarithms?

    • “a” and “b” are two positive real numbers
    • y is a real number
    • “a” is called argument, which is inside the log
    • “b” is called the base, which is at the bottom of the log.

    How do engineers use logarithms?
    Engineering Connection. All types of engineers use natural and common logarithms.Chemical engineers use them to measure radioactive decay, and pH solutions, which are measured on a logarithmic scale. Exponential equations and logarithms are used to measure earthquakes and to predict how fast your bank account might grow.

    How to calculate logarithms?
    Calculating Logarithms By Hand W. Blaine Dowler June 14, 2010 Abstract This details methods by which we can calculate logarithms by hand. 1 De nition and Basic Properties A logarithm can be de ned as follows: if bx = y, then x = log b y. In other words, the logarithm of y to base b is the exponent we must raise b to in order to get y as the result.

      Logarithms are easy to compute in some cases, such as log10 (1000) = 3. In general, logarithms can be calculated using power series or the arithmetic–geometric mean, or be retrieved from a precalculated logarithm table that provides a fixed precision. Newton's method, an iterative method to solve equations approximately, can also be used to calculate the logarithm, becaus…
