### I need help with the fx-115 ES on how to find what to hit to input calculation for antilog

Use the shifted function of the appropriate log key (log for common (base 10) log/antilog and ln for natural (base e) log/antilog). For example, to calculate the common antilog of 2, press SHIFT log 2 = and to calculate the natural antilog of 2, press SHIFT ln 2 =.

### WHERE IS ANTI.LOG ON MY CALCULATOR

The common (base-10) antilog is the shifted function of the "log" key on the third row of the keyboard, just above the "cos" key. The natural (base-e) antilog is the shifted function of the "ln" key just to the right of the "log" key. The two antilogs are marked "10^x" and "e^x", respectively.

### How do you use the -log function on the TI-30XA calculator? I downloaded the manual and there is no instruction for finding the -log of a number

Do you mean the antilog? For the common antilog, use the shifted function of the LOG key (marked 10^x). For the natural antilog, use the shifted function of the LN key (marked e^x).

For example, to calculate the common antilog of 0.5, press . 5 SHIFT [10^x] = and get about 3.16. To calculate the natural antilog of 0.5, press . 5 SHIFT [e^x] = and get about 1.65.

### How to find antilog on casio fx-991MS?

For common antilog, use 10^x, the shifted function of the log key. For natural antilog, use e^x, the shifted function of the ln key. In either case, press the appropriate function and then enter the expression whose antilog you're seeking.

### Where is the antilog button? I need to input antilog and i dont know how.

The common antilog is the 2ND function of the common log (LOG) key, just to the left of the 7 key. The natural antilog is the 2ND function of the natural log (LN) key, just to the left of the 4 key.

### I am trying to find out where is

Hello,

1. Let y=10^(x) ( 10 raised to the power of x)
2. Take the log of both tems of the equality.
3. You getlog(y)=log[10^(x)] where I used square brackets for clarity.
4. But from the general properties of logarithmslog(b^(a)) = a*log(b)
5. Applied to our expression above ( in Number 1)log(10^x)=x*log10
6. But since we are using log as log in base 10, log_10(10)=1 so log(y)=x
7. We thus have two equivalent relations y=10^x <----> x=log(y) The double arrow stands for equivalence.

If y is the log of x, then x is the antilog of y

Let's get back to you problem : To obtain the antilog you use the key marked with a 10^x.

Exemple1: What is the antilog of 3
Answer: Antilog(3) =10^3 =1000 because log(1000) =3.

Exemple 2: What is the antilog of 1.543765?
Antilog(1.543765) = 10^ (1.543765)= 34.97558603

Exemple3: What is the antilog of -0.37654?

Look on the body of the calculator if there is key or a [Shift] key labeled with 10^x ( a 10 with a small raised x). If you are able to find it, use it. If not, you can always use the [raise to the power key] ( a caret ^, or Y to the x or X to the y.) For the last exemple, you type it as follows.
10 [^] (-) 0.37654 [=/ENTER]. The (-) is the change sign not the regular Minus.

Hope it helps.
Thanks for using FixYa.

### How to calculate the antilog please

The antilog is the inverse of the logarithm. Not too surprisingly, it's invoked as the 2ND shift of the appropriate log key.

For the common antilog, use the 10^x key (2ND LOG). For example, 2ND LOG 3 ENTER gives 1000 as the common antilog of 3.

For the natural antilog, use the e^x key (2ND LN). For example, 2ND LN 3 ENTER gives 20.08553692 as the natural antilog of 3.
