Question about Texas Instruments TI-30XA Calculator

# 1.009 to the 17 power and higher

My TI-30XA calculator doesn't have the y^x or any carat sign to help me raise a # to a higher power than 10. I only have 10^x, e^x, and x^3.

The TI-30Xa has a "y^x" key located just above the divide key. To calculate 1.009 to the 17th power, press 1 . 0 0 9 y^x 1 7 =

look for a key that has this symbol ^ this is often called a carrot. it's somewhere in the middle and on the right. go 10^21

Nope, there's a download online at TI's website but it's the same as the one that comes with the calculator.

Hello,
Use the Y to the x key [Y^x]. To enter the negative exponent use the change sign key [+/-] not the regular minus - sign.
Hope it helps.

Two ways:

1) hit the equal sign

2) hit 2nd and [d/c] (you can do this multiple times to see it as the most reduced improper fraction or as a mixed fraction)

There's a key marked y^x (y-superscript-x) to raise a number to any power.

### When I raise 6.022 to the 23 power on my calculator (TI-30XA) it says error

It should not, unless you entered it the wrong way. Use the key marked [^] or [X^y] or [Y^x].
It is none of my business but I think you are trying to type in Avogadro's number. If that is the case then you should use the [EE] key to enter the power of 10.
Type 6.022 [EE]23 (Notice that there is no 10 to enter; the EE key is a shortcut for [*10^ ] .)

### How do i find the negative log on a TI-30Xa

Hi,

Ex: calculate -log(15.32)
1. Calculate the log 15.32 [LOG] [=] result 1.185258765
2. Then press the change sign key (-) result -1.185258765
You can also try 15.32 [LOG] (-) [=]. Try to veriufy it on your calculator.

Here is a picture of the change sign Hope it helps

### How to use antilog?

Hello,

As you well know the pH is the negative of the log in base 10 of the H+/H3O+ ion concentration. If we use [H+] to represent that concentration, then pH=-log[H+].
To obtain the [H+] you need to calculate the antilog. You write the definition in the form log[H+] =-pH and then calculate 10 to the power of each member. The equality remains valid as both members are treated similarly. Thus
10^( log[H+] ) = 10^(-pH)
Since raising 10 to a power is the inverse function of taking the log in base 10, 10^(log(x))=log(10^(x)) = x (they are inverse of one another), you are left with

[H+]=10^(-pH)

Your calculator has a function [10 to x] accessed by pressing the [2nd] function key. To use it you must enter the negative value of the pH, press the [2nd] function key then the [10 to x], then the = key to get the result (concentration)
Exemple: let the pH=5.5, what is the H+ concentration?
With [(-)] being the change sign key, then
[H+]:[ (-) ] 5.5 [2nd][10 to x] [=]
The result is 0.000003162 or 3.16 x 10^(-6)

Hope it helps.

### How can i raise to a negative power on TI-30xa

Hello,
Use the Y to the x key [Y^x]. To enter the negative exponent use the change sign key [+/-] not the regular minus - sign.

### How do you do this exponent?

If you mean 3 raised to the power 375, sequence is

3
y to the power x (under OFF key)
375
=

Answer is "error" because the result exceeds the 9.9999.... times 10 to the power 99 limit of the TI-30XA

3 to the power 209 is about as far as you can go....
