# Casio FX-100AU Is there something wrong with my calculator? Trying to use the log function... what sequence do I press to solve... 20log (2/10mv) to get the textbook answer of 46db? Thanks

Posted by on

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

### How to use antilog by casio fx-82es

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]

### How to use log values in calculators

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.

### How to find nth root using Casio FX-83ES

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.

### Trying to get the inverse of a matrix

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
