Question

how to do logarithm in easy way

Answer 1

1

Know the difference between logarithmic and exponentialequations. This is a very simple first step. If it contains a logarithm (for example: logax = y) it is logarithmic problem. A logarithm is denoted by the letters "log". If the equation contains an exponent (that is, a variable raised to a power) it is an exponential equation. An exponent is a superscript number placed after a number.Logarithmic: logax = yExponential: ay = x



2

Know the parts of a logarithm. The base is the subscript number found after the letters "log"--2 in this example. The argument or number is the number following the subscript number--8 in this example. Lastly, the answer is the number that the logarithmic expression is set equal to--3 in this equation.[2]

Know the difference between a common log and a natural log.Common logs have a base of 10. (for example, log10x). If a log is written without a base (as log x), then it is assumed to have a base of 10.Natural logs: These are logs with a base of e. e is a mathematical constant that is equal to the limit of (1 + 1/n)n as n approaches infinity, approximately 2.718281828. (It has many more digits than those written here.) logex is often written as ln x.Other Logs: Other logs have the base other than that of the common log and the E mathematical base constant. Binary logs have a base of 2 (for the example, log2x). Hexadecimal logs have the base of 16 (for the example log16x (or log#0fx in the notation of hexadecimal). Logs that have the 64thbase are indeed quite complex, and therefore are usually restricted to the Advanced Computer Geometry (ACG) domain.
