Question about Casio FX-300MS Calculator

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

Sorry I don't know anything about it personally. The manual should help.

For common logs (logs in base 10) use the 10^x function : Press [SHIFT] [Log] to access it.

For natural logs, use the exponential function. Press [SHIFT][ln] to access it.

The inverse of the log function is the function 10^

antilogarithm of (x)=10^(x)

The function shares the same physical key as the [LOG] function. To access it you press [SHIFT][LOG].

The antilogarithm of the natural log [LN] is the exponential function [e^x]. It shares the same physical key with the [LN] function. To access it press [SHIFT][LN]

You have two keys [LN] and [LOG], the former to calculate the natural logarithms and the latter to calculate the logarithms in base 10.
You press the appropriate function key then type in the value. No need to press the [=] sign.

In case you are wondering: these functions have inverses: the inverse function of [LN] is the exponential, accessed with the key sequence [SHIFT][LN]; the inverse function of the logarithm in base 10 is "raise to to a power", accessed with the key sequence [SHIFT][LOG].

I am enclosing a screen capture from the user's manual. It shows you several examples.

You use the power root function key accessible with the key sequence [SHIFT][X ^]. I am inserting a screen capture from the manual to show you the sequence.

On the third line of the capture (power root) is the key you must press. In the small rectangle to the left of the radical sign you enter the order of the root: 2 for square root, 3 for cube root, 4 for 4th root and son on.

To calculate the decimal log you use the [LOG] key as shown on capture. For natural log (ln), use the [LN] key. The argument (2/3) in your example should be enclosed inside the parentheses.

Hello,

The error may be due to the key you used to signifie inverse. It says in the manual that you should use the key x^-1 not the one used to input general powers.

Here is screen capture from the Appendix to the manual. The picture shows the sequence of keys to press to obtain the inverse of a 2x2 matrix. It is taken from page 41 of Appendix

The matrix used in the exemple is

a_11=2 a_12=1 a_21=1 a_22=2

Here is the link to download the manual and the appendix

Hello,

If you have the Replay button, you can go back, as long as you did not turn off calculator. There is a limit on how far back you can go.

Hope it helps.
