How to fix error mesage on TI-30Xa. Every time I press LOG an error sign comes up. how do i fix this?

To take the log of a number, enter the number then press the LOG button, then the =. To take the log of a negative number, enter the negative number using the +/- key just to the right of the decimal point. To calculate the negative of a log, calculate the log and then negate it using +/-. To calculate the antilog (inverse logarithm), press 2nd then LOG.

Bear in mind that LOG is the common (base-10) logarithm. For the natural (base-e) logarithm, use the LN key to its right.

Where is the inverse button on a TI-30XA calculator?

It is the second function of the Pi button.
First you have to push the yellow 2nd button and after the Pi button.

I hope it helps.

I am trying to raise 0.92 to the power of 10, I cannot find the button anywhere on my Texas Instruments TI-30XA calculator. There is no y^x button on my calculator, please help.

Use the (y to the x) button, just under the off button.

Enter 0.92 press (y to the x) and then enter 10 and =.

I hope this helps you out.

How do i divide by powers of 10 in my TI-30XA calculator?

The same way you would divide by any other number. Just use the EE key (just above the 7) to enter the exponent. If the exponent is negative, use the +<>- key (just to the left of the =) to enter the negative sign.

Decimals in the exponents for TI-30Xa

You have a key labeled [Y to the x], use it for all the powers or roots that do not have a dedicated key or key sequence. Let the key be [^]

Ex: 13.675 to the power 1.33 is entered as 13.675 [^] (1.33) [=].
The result is 32.41778634
Ex: (-64)[^](2/3) [=] gives 16 as result. The (-) is the change sign key
Ex: (2.87655)^(-6.778) is entered as 2.87655 [^] ( (-) 6.778 ) [=] 0.0007758
The (-) is the change sign (or the negative of), not the regular minus. When you have a negative exponent or a complicated exponent, it is safer to enclose the whole exponent inside parentheses.

Hope it helps.

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

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.

How can i enter 3 to the negative 2 power

Hit the buttons in this order:


You can also find 3 to the second power and then divide the number 1 by your answer.

Since y^-x is the same as 1/y^x

Hope this helps.

How do I get a negative number?

  1. Press the fourth bottom grey key.  It has a + and -  in it with some arrows right next to a green key.

Scientific notation

You have to use the EE button right next to the parenthesis and the sigma plus button. So 1.7 EE and then your exponenet. If it is a negative exponent you need to hit the negative button before you type in the number.
