SOURCE: log2(0.25)

Unfortunately the 531 cannot do this calculation. you need to first convert the log into a base 10 log - this means it will be log 0.25 divided by log 2 and it should give you minus 2.
However, if you would like a calculator that can do that calculation directly, try out the EL-535.

If you have any more questions there is a dedicated website http://www.mathsatsharp.co.za/ where you can leave questions about the SHARP calculators on the student page and they will be answered within a week maximum.

The Casio FX-300MS does not provide base 2 logarithms as a single key operation. However, you can use the natural logarithm (ln, base e = 2.7182818...) and the formula

log2 ( x ) = ln( x ) / ln( 2 )

To calculate the base 2 logarithm of 16, key in
[ln] 16 [/] [ln] 2 [=]
and get displayed the correct answer 4.

The same simple formula also works for any other base, and actually for any other logarithms provided by your calculator. The FX-300MS also provides a logarithm to base 10 (lg). You could also
type
[lg] 16 [/] [lg] 2 [=] to get the solution to the problem above, or
[lg] 25 [/] [lg] 5 [=] to get the base 5 logarithm of 25.

How can I calculate Log2 2.5 on my calculator.. since everytime I start entering it i start by pressing log and right away it says ERROR.. by the way the 2 right after log is suposed to be a little 2.


First of all, to compute the log of a number, enter the number first then press the LOG key.

Second, to compute the log to a base b other than e or 10, use the relationship
logb(x) = log(x) / log(b) = ln(x) / ln(b)
You can use either the common log (log) or the natural log (ln), as long as you're consistent.

So, to calculate log2(2.5), press
2 . 5 log / 2 log =
or
2 . 5 ln / 2 ln =

How to type log base 2


You can't. However, you can calculate the log base 2 of any number by calculating

log2(x) = log(x)/log(2) = ln(x)/ln(2)

That is, the log base 2 of any number is the log of that number divided by the log of 2.

You cannot do it with a single key. Rather you use the relation
log in base a of b = log_a(b)=log(b) /log(a)
So log2 5 =log(5)/log(2)

How do you calculate log in any base


Use Diamond + LN or Diamond+7 to get the decimal log().

use the second argument as the base, for example:

log2(64) = log(64,2)

Log2 x = 2.5


If the Log2 stands for log in base 2.then
2^(log2 x)= 2^(5/2)
But 2^ (log2 x) =x, so solution is x =2^(5/2).
All that is left for you to do is to calculate 2^(5/2) or 2^(2.5) or square root of (2^5) or square root of 32. and you find x.

Log I do not know how to...


I have finally worked out how to do log to the base 2 on my FX-83ES after nearly 2 years.
I hope yours is a similar problem.

The calculator must be in MATH mode or it will not work.
press the log button as the useless manual says then 2 then the right arrow on the replay button and then the number you want the log2 off..
Hey presto a correct answer

How to calculate log value in calculator with different base value


In any scientific calculator log2(n) can be  calculated with either ln or log function as follows
 
Log2(n)= ln(n) / ln(2)
 
Or
Log2(n)=log(n) / log(2)

both will give nearly the same answers
