Question

What do you mean by log.?

Answer 1

logarithm or computer one...???

Answer 2

In its simplest form, a logarithm answers the question:

How many of one number do we multiply to get another number?

Example: How many 2s do we multiply to get 8?

Answer: 2 × 2 × 2 = 8, so we needed to multiply 3 of the 2s to get 8

So the logarithm is 3

How to Write it

We write "the number of 2s we need to multiply to get 8 is 3" as:

log2(8) = 3

 

The number we are multiplying is called the "base", so we can say: 

"the logarithm of 8 with base 2 is 3"or "log base 2 of 8 is 3" or "the base-2 log of 8 is 3"Notice we are dealing with three numbers:the base: the number we are multiplying (a "2" in the example above)how many times to use it in a multiplication (3 times, which is the logarithm)The number we want to get (an "8")
