math of logarithms. Therefore 3 is the logarithm of 8 to base 2 or 3 log 2 8. In mathematics the logarithm is the inverse function to exponentiationThat 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 xIn the simplest case the logarithm counts the number of occurrences of the same factor in repeated multiplication.
Eg since 1000 10 10 10 10 3 the logarithm base. The intent of logarithms is to help simplify calculations in areas such as science engineering physics and mathematics. These seven 7 log rules are useful in expanding logarithms condensing logarithms and solving logarithmic equationsIn addition since the inverse of a logarithmic function is an exponential function I would also recommend that you go over and master.
Exponents and Logarithms are related lets find out how.
For example the base 10 logarithm of 100 is the number of times youd have to multiply 10 by itself to get 100. In this definition y logbx y log b x is called the logarithm form and by x b y x is called the exponential form. Therefore a x n can be expressed in logarithmic form as. It is called a common logarithm.
