SOURCE: 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

The casio FX-570MS does not handle matrices. So you cannot create matrices, let alone invert them. Sorry.

The Casio FX115 ES handles matrices for up to 3X3 dimension. Create the matrix.Have its name displayed on the command line and press the [x^-1] (reciprocal ) key.

Hello,

Sorry I clicked the post a clarification request too fast.

You cannot compute it directly. You have to use the formula

log_18(number) = ln(number)/ln(18).

Here log_18 is log in base 18, ln is the natural logarithm (naeperian or log in base e).

Alternatively, you can use

log_18(number) = log(number)/log(18)

where log is log in base 10.

If you use those types of calculations a lot, it might be a good idea to get a Casio FX-115ES, or a Casio FX-991 ES. They have other nice features like fraction calculations and radicals.

Hope it helps.

Hello,

There is something missing in the formulation.

Any way you cannot calculate it directly on this calculator.You need to use the formula

**log_5 (a)= ln(a) x log_5 (e) **a is a positive integer

where** log_5** means log in base 5 (my notation for the function)

**e** is the base of the natural logarithms (e=2.71928 )

**ln** is the natural log function

To obtain a more accurate value of e, calculate e^(1)

Here are some values of log(e) in different bases (for you to play with)

log_2(e)= 1.442695041

log_3(e)=0.9102392266

log_4(e)=0.7213475204

log_5(e)=0.6213349346

log_6(e)=0.5581106266

log_7(e)=0.5138983424

log_8(e)=0.4808983470

log_9(e)=0.4551196133

log_10(e)=log(e)=0.4342944819

If you have to use log in bases other than 10 or e, you will need a claculator that does that at the touch of a button. Some calculators that handle these calculations are the Casio FX-300ES, FX-115ES,FX-991ES, those called Natural Display, or WriteView(Sharp) or Textbook display.

Hope it helps.

Like you maybe know in math (I know!) log x base y = log x / log y

so what you need its just input your number (x for example) and log it, than divide log x by log 2.

just: log x / log 2. (by the way in calculator the meaning of log x is log x base 10 the default base is 10)
