Question about Texas Instruments TI-30XA Calculator

# Exponent key I am trying to multiply and divide using the exponent key-I ws using the EE key, then someone pointed out I was wrong and now...I am confused. the problem is 1.01 x 10 to the 11th power divided by 6.20x 10 tot he 23rd power. HELP! thank you SO much!

On the Upper right corner, below the OFF button.
Key in the number, press that YtotheX key, and input the integer. Press =. That is your answer.

### How are numbers in scientific notation entered in Aurora SC150X calculator

Look for a key that is marked EE, or Exp, or x10^x. To enter a number in scientific notation, you enter the decimal part, then press the Enter Exponent key, followed by the exponent. If exponent is negative, you precede it with a press of the change sign key (-).
Once a number is entered there is no special treatment: multiply it divide, or add it.

### I need step by step instructions on using Casio fx-115ES ee or exp burron.

The equivalent of the EE or EXP button on the Casio Fx-115ES is marked as x10^X. It is located at the bottom right of the key pad left of the = key.
To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.
Example Enter the mass of the proton m_p in kilograms
1.6726217 [x10^X] [(-)]27 [=]
In grams the value above is multiplied by 1000.
or
1.6726217 [x10^X] [(-)]24 [=]

Since the calculator has the physical constants (the FX-991ES definititely has them)
1. Display the proton mass in kilograms
2. [SHIFT ][7] to open the constants catalog,
3. type 01 for the proton mass, then press the [x^-1].
4. Divide the result by 1000
5. You should get 5.978638635 x10^23

### How to enter exponents

If you mean an exponent of ten, use the EE function (the shifted function of the "," key, located just above the "7" key. For example, to enter 1.2 times ten to the negative 3, press 1 . 2 2ND [EE] (-) 3

To raise a number to an exponent, use the ^ key located just above the divide key. For example, to calculate 3 raised to the 4th, press 3 ^ 4 ENTER

### How do I find the square root of a number? and how do I enter scientific equations?

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

### How do I enter an arbitrary exponent on the ti-84?

If you mean an exponent of ten, use 2ND EE (located on the SIN key just above the 7). If you're raising an arbitrary number to a power, use the ^ key just above the divide.

In either case, if the exponent is negative, make sure you use the (-) key to the right of the decimal point instead of the - key.

### Try to multiply (20x10-9) (1x10-9)

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

### I need to find out how to use the powers button. for example 10 to the 23 power. but I don't know where the button is and how to use it.

There's a key marked "EE" (for Enter Exponent) just above the "7" key. This key is used to enter decimal exponents. To enter 1x10^23, press 1 EE 2 3

For exponents to other bases, use the y^x key just above the divide key.

### EE button ("enter exponent" button) Retuns Wrong Value

Hello,
I dont think you got a lemon.
You acn always enter the powers of 10 as 10, [y^x], but is is less efficient than the EE key
This EE representation is a shortcut.
If you want 10 to the 5th power you just enter [2nd] [EE] 5 and the calculator displays 100000. Of course if you need any other number multiplying the power of ten you enter the following e.g. 2.677[x][2nd][EE]5.

You will not get any error with a positive exponent. But if your exponent is negative you should use the change signe key to the left of ENTER and symbolized by (-)

To avoid all errors I would use parentheses to enclose my exponent.

Here is how to explain the seemingly erroneous result

10 [EE] 5 ) (-) is interpreted by your calculator as 10x(10^(-5)) which evaluates correctly to 0.0001 because [EE] by itself stands for 10^ .

Hope it clarifies this point for you.

By the way some new calculators (Casio) don't have this EE key. Instead you find a key labeled x10^X .

Hope it helps
