What is the meaning of log?

Answer 1

of Log, The business of felling trees, cutting them into logs, and transporting the logs to sawmills or to market.

Answer 2

In logarithm 1 means 10 to the power 0,10 means 10 to the power 1,100 means 10 to the power 2. 1000 means 10 to the power 3. 1000,0 means 10 to the power 4. 1000,00 means 10 to the power 5, 100,000 means 10 to the power 6. So very large numbers or very small numbers can be written by this method. If you have to write a number, say 1 fallowed by billion zeroes, instead of go onwritingbillion zeroes in front of 1, you can simply write 10 to the power 1 billion.Now you can come to small number. 0.1 means 10 raised to power minus 1. 0.01 means 10 raised to the power minus 2. 0.001 means 10 raised to the power minus 3. So for 10 raised to the power minus 1 billion you can write as 0.0000.......such billion minus one zero fallowed by 1. Soinsteadof this you would always prefer to write 10 to the power minus 1 billion. This will be extremely small number very near to zero. But 'not' zero. If you want to write negative small or large number, then you can put minus sign before the number. You can use 2 as a base instead of 10.

Answer 3

In mathematics, the logarithm function is the inverse of the exponentiation function, and it gives the power to which a given base must be raised to obtain a specific number. Logarithms are used to solve exponential equations and to simplify calculations involving very large or very small numbers.
