The base should be the same for both the numbers. The division of the two numbers is the antilog of the difference of logarithm of the two numbers. Proof: Let log b x = p such that b p = x … (i), andī p × b q = x × y = b (p + q) The logarithm of the product of two numbers say x, and y is equal to the sum of the logarithm of the two numbers. Solving System of Equations by Cramer’s Rule.Quadratic and Cubic Equations in One Variable.Simultaneous Linear Equations up to Three variables.Browse more Topics under Business Mathematics For example, if 2 4 = 16, then 4 is the logarithm of 16 with the base as 2. In other words, if b y = x then y is the logarithm of x to base b. The power is sometimes called the exponent. Let us study logs and antilog in detail.Ī logarithm of a number is the power to which a given base must be raised to obtain that number. Logarithms and Anit-Logarithms are the inverses of each other. The changed number can be put into original form by using antilog. To make long, tedious and confusing calculations simple, we change the form of the number using logarithms. It is not always possible to handle the numbers which are either too large or too small. 2 Solved Examples on Logarithms and Anti-Logarithms Logarithms and Anti-Logarithms
