Okay, so I'm trying to fix my exponents over here. I needed to find out what 0.77 is to the 22nd Power...so i put it in my calculator and get this CRAZY number: 3.18270183 x 10^03...What the hell???? How did I get that when my teacher got 0.0032? I want this to be simple! I have a math test on Tuesday and this is the kind of math Im going to be dealing with on the test and my calculator's being difficult. How do I change the setting to this?? Please help =[

If by power, you mean exponents, there are several rules.

Multiplication with the same base - add the exponents
Division with the same base - subtract the exponents
Exponent to an exponent - multiply the exponents
Negative exponent - 1 over the same number to the positive exponent
Zero exponent - anything to the exponent 0 is 1

Good luck,

Paul

I don't have this calculator, but let's give this a shot and see if it gives us the correct answer.

Let's try 10 to the exponent -2. The rule for negative exponents is to put 1 on the top and the term with a positive exponent on the bottom. In this case, it would be 1 on the top and 10 to the exponent 2 on the bottom, or 1 / 100 or 0.01.

In the calculator, enter 10, hit the x to the power of y key, left bracket (, the negative key (-), 2, the right bracket ), and finally the = key. You might not have to enter the left and right brackets, but I like to enter them to understand what I enter in brackets is the exponent.

Let me know if it works and if you have any other questions.

Good luck.

Use the ^ key, located above and left of the 7 key. For example, to calculate 2 raised to the 120 power, press 2 ^ 1 2 0 =

Depending on your version of the TI-30, you will either find a button with a y to the exponent of x or a button that is the carot (^) sign. you would type (1.0075)^(-240), where ^ is the appropriate button (y^x or just ^).

You're not raising a negative number to an exponent, you're negating a number raised to an exponent.

If you want to raise -2 to the second power, you need to enter it as
( (-) 2 ) ^ 2

Without the parens, what you're getting is the equivalent of -(2^x)

If you use the exponent rules you do not need to use a
calculator for this particular case. Anyway to enter power of 10 exponents you use the [EE] key. See screen capture below.

20 [EE] (+ -)9 [X] 1[EE] (+ -) 9

1 . 0 1 5 y^x 1 8 =

Hello,
Use the small (-) sign sometimes labelled [(-)] or [+/-] and put the whole exponent netween parentheses 18 [y to the x] [(] [(-)] 3 [)] . On some calculators you enter the small - signe after the value of exponent,
18 [y t x] 3 (-) [Enter] should give you 1.7146E-4
In summary the small minus sign; the whole negative exponent between parentheses.
Hope it helps.

On the TI-36X there is no rooftop key, there is a yx key. This key is two keys below the on button. To use it, put the number in, press the yx key, put the exponent in, press the equal button.

For 5 to the 6th power, type
5 ^ 6 =
You should get 15625
