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.

It's been a while since my TI calculator died, but I think you can just hit EE (may be "exp" on your model) followed by =.

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

### How do I do exponents on this calculator?

Two keys can be used to enter negative exponents on the TI-30Xa scientific calculator; the [y^x] key or the [EE] key. The [y^x] key is used for all exponents while the [EE] key is used for scientific notation only.
The examples below will demonstrate how to use both keys:

1) Entering 7^-2.

• Press [7] [y^x] [2] [+/-] [=].
• The calculator will display: 0.20408163.
2) 1*10^-3.

• Press [1] [EE] [3] [+/-] [=].
• The calculator will display: 0.001

### How would type in scientific notation?

Use the EE key (just above the 7 key) to enter an exponent. For a negative exponent, use the +- key (just to the right of the decimal point key) to enter the negative sign.

For example, to enter 1.2 x 10^-21, press 1 . 2 EE +- 2 1

To switch the display mode to scientific notation, press 2nd [SCI] (the 5 key).

### HELP, I can't seem to figure out scientific notations with my Texas Instrument TI-30XA. I've searched for hours on the web. Here's the problem: 7.82 x 10^10 / 63.55 = 1.23 x 10^9. But when I input 7.82 x...

Hello,
The error comes from the lack of understanding of the meaning of the notation used by the calculator manufacturers.
The [EE] is a "shorthand" notation for times 10 to the power of .
To convince you of it try entering

1[EE]0 [=] this is 1*10^0=1*1=1
1[EE]1 [=] this is 1*10^1=1*10=10
1[EE]2 [=] this is 1*10^2=1*100=100

When you enter 7.82x10[EE]10
you are calculating
7.82*10*1*10^10=7.82x10^11.

Hope it helps.

### Inputing Scientific Numbers

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
