I am trying to resolve math.question but I am stuck because do not know where on calculator is" antilog"

I am trying to find out where is "INV","shift" or 2nd +log.please help me.

Hello,

**Please read the following with patience.**

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

If

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?

Answer: Antilog (-0.37654) =10^(-0.37654) =0.4202038237

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.

The antilog functions are the 2nd functions of the log functions on the top row of the keyboard.

To calculate the natural antilog of 3.1, press 3 . 1 2nd LN

To calculate the common antilog of 3.1, press 3 . 1 2nd LOG

To calculate the natural antilog of 3.1, press 3 . 1 2nd LN

Make sure you use the (-) key to enter negative values, not the - key. For example, to calculate the common antilog of -5, press

SHIFT log (-) 5 =

To calculate the natural antilog of -5, press

SHIFT ln (-) 5 =

SHIFT log (-) 5 =

To calculate the natural antilog of -5, press

SHIFT ln (-) 5 =

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 =.

Antilog is a somewhat outdated terminology for the inverse function of the logarithm.

To calculate on your FX-115ES the base 2 antilog of 4, key in

Correct result is 16.

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.

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.

press shift log and then u can use antilog and give the numeric for which u have to find antilog then press = thats all
if u are satisfied with the answer pls rate the session

"2nd" + "log"

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.
