SOURCE: Casio FX-100AU

Just input #20 then press log button then (2/10 shift 5 (m)) so it will look like 20log (2/10m) = 46.02

SOURCE: Inputing factors on a casio fx-115es calculator

Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

SOURCE: want to solve quadratic equations on my casio 3650p super fx

Hello,
In your manual, Appendix Program Library, (Page A1) you have the listing of the problem to solve the quadratic equation. Type it in your calculator and execute it.

SOURCE: Why does it solve in fractions?

The calculator has two Input/Output modes: the default MthIO (new) and the old LineIO.

  1. In MthIO you enter fractions and radicals as you see them in textbook (multiple levels). Calculations are exact and results are generally a mixture of fractions and radicals.
  2. In LineIO, numbers are entered the old way and all numbers, operations are written on a single line. All fractions and radicals are converted into decimals numbers.

If you use the default MthIO you can let your calculator perform the operations in exact arithmetic. When you obtain the end result, you can easily convert a fraction/radical result into a decimal one by pressing the [S<=>D] key, or press [SHIFT][=] instead of [=].

However if you do not care about the MthIO and its nifty functionalities, you can configure your calculator to use LineIO.

To set LineIO press [SHIFT][MODE][2:LineIO]

How to solve logarithms on a casio fx_9750gii?


You calculate logarithm by using the log key for decimal logs and the ln key for natural logs.

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.

I have a Casio fx-82au plus and want to input logs to the base less than 10. Is there a way to do this? eg log to the base of 2 = 16 (answer is 4 but how do we get that to work on this calculator).


You can calculate the logarithm to any base by using the relationship
logb(x) = log(x)/log(b) = ln(x)/ln(b).

To calculate the log base 2 of 16, either divide the log of 16 by the log of 2 or the ln of 16 by the ln of 2.

I do't know how to punch my casio fx-350MS to solve log and ln proplems. for example 1. log10y given the answer to be 0.4343..., 2. ln2/3, ln1/30 given the answers (-0.405) and (-3.401) respectively


You seem to be doing it correctly. The natural logarithm of 2/3 is about -0.405 and the natural log of 1/30 is about -3.401.

As for the common log of 10y, that would depend on the value of y. If y is e/10, then the log of 10y would be about 0.4343.

What steps should I use to get the answer for the following using my Casio fx-115ES: [(In(1.02)-In(0.71)squared divided by 3.92 squared]? Thanks!


Enter it almost exactly as you typed it. Just remember that ln will automatically enter the left-parenthesis, and that you don't need to close all parenthesis before pressing =.

( ( ln 1 . 0 2 ) - ln 0 . 7 1 ) x^2 / 3 . 9 2 x^2 =

How to calculate 0.3log(base 2)0.3 using fx-991ms calc


Your calculator knows only the decimal logarithms log or log_10 and the natural logarithms (ln or log in base e).
So you cannot compute directly the logarithms in any bases other than 10 and e.
A workaround consists in using the relation
log in base b of a number a (log_b (a))
log_b(a)= (log_10(a) ) / (log_10 (b))
or the relation
log_b(a)= ln(a)/ln(b)

log_2(0.3)=log(0.3)/log(2) where log is log in base 10
Similarly
log_2(0.3)=ln(0.3)/ln(2)
As to the multiplicative factor you had at the beginning of your expression, just multiply the value obtained by one on the formulas above (both formulas will give the same result) by 0.3
