But what about
2^9 = 512
2 × 1 = 2, and
This quite major result, simply explained, leads to the best-known rule with logarithms:
What is 2^3 × 2^6 ?
It is too notable that the first differential of log(x) is 1/x. (This is true when the logarithm bottom is "e", the sum of the series
By the same token [link widoczny dla zalogowanych], it is fairly handy to write
2^3 × 2^6 = 2^9, or
"Math Made Nice & Easy #2: Percentages, Exponents, Radicals, Logarithms and Algebra Basics"
2^(3 + 6) = 2^9
(2 2 2) (2 2 2 2 2 2) = 512, alternatively 2^9, so
Logarithm References
Logarithms are 1 of the maximum profitable tools in pure and applied numbers. They are accustom throughout all of science and engineering, and comprehending them is fussy for anyone scientist or engineer. They are also a reason terror fall butme students. This story tries to annotate them simply.
The same can be shown because 2^1 2^8, or 2^2 2^7 etc. In additional words, it doesn't stuff which teams are put into brackets - the result is the same.
1 + 1/1 + 1/2! + 1/3! + ...
In words, this is "two to the power of 9 equals five hundred and twelve". The logarithm in this example is defined as the power to which 2 must be raised to get 512 [link widoczny dla zalogowanych], or "how many times must 2 be multiplied by itself to get 512.
2 × 2 = 4, but what about
It is this result that allows colossal numbers to be multiplied or divided using logarithms.
9 × 1 =9
1 + 1 = 2
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9 ?
2 2 2 2 2 2 2 2 2 = 512, we can derive one of the elementary rules of logarithms:
It is true namely the sum is 9, merely it is hugely inconvenient apt write. What if the aggregate was 1,000 or 1 million? A access needed apt be found to write down the answer in synopsis fashion. So the amplify ("") sign was used:

Logarithms hold fear for many students - but they ought no. They are nobody extra than a short-hand way to write down someone that would otherwise take also much time and space. This article explains why the exponent (power) rules and the rules of logarithms are true, and why they ought be effortless to understand.
Logarithms are not a stand-alone, separate fancy. They are portion of a catena of "convenient ways of writing". The first "summary" is really multiplication:
2 × 2× 2× 2× 2× 2× 2× 2× 2 = 512 ?
When teaching logarithms to students who are watching them for the first time, it is useful to obtain them to write out the long-hand means first (e.g. 2 2 2 2 2 2 2 2 2) . Doing this with by least 5 instances, and then granting them to write 2^9 etc [link widoczny dla zalogowanych], truly shows the benefits of manuscript the short-hand edition. This also de-mystifies the exponent symbol.

Logarithm Summary
log(x) + log(y) = log(x × y)
Using the previous example
Methods to show this were contrived too. The caret ("^") character is used where superscripts are unavailable:
where 3! (3 factorial) is 3 x 2 x 1).
