### For my homework i have to figure out what the exponential form is for 16

I am not sure what you mean. Even politicians use the term exponential so it has become blurry.
16=2^4 The power function is related to the exponential.
16=1.6*10^1 Scientific notation. Scientific notation is an exponential display format.

### Casio fx-115ms OR ANY scientific calculator

Engineering notation ALWAYS puts the exponent as a multiple of three (kilo, mega, giga, etc). If you want the exponent as it is, use scientific notation. You can put the fx-115EX into scientific notation by pressing SHIFT MODE 7 and then entering the number of digits you want after the radix mark. Unfortunately there is no way to have the calculator adjust both the mantissa and exponent by anything other than three.

Press 2nd [SCI] to switch the calculator to display all results in scientific notation. The results are the same whether you do it in scientific notation or not, it's just how the number is displayed.

### I don't know how to use the calculator enough to figure scientific notations

Scientific notation is a number format that has the following structure (d stands for digit)
one digit decimal mark several other digits [times] 10 raised to power of exponent
d [decimal mark] dddddd...[x] 10^ (-) dd

Here are two examples the last two results. The number of digits after the decimal mark is select by the user depending on the number of significant digits in the data. The exponent can be positive or negative.

In you case, to enter x10^ you press the [EE] key (no 10 is entered) the sign of the exponent and the value of exponent.

### 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.

### Scientific notation

Hello,
Use the EE key
1.234[EE] [(-)]65 [ENTER] 1.234 times 10 negative 65 =1.234E-65
The (-) is not the regular (bigger) minus sign.
Hope it helps

### Inputing scientific notation into my calculator

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

### 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....

### Chemistry problem

You enter a pH value and change the sign to minus, then hit 2nd LOG which is 10^x. The x value is what you're looking for. To put the answer in scientific notation, press 2nd 5 to do so.

Example:

For a pH = 4.1

-4.1 2nd LOG will return 0.0000794

Hiting 2nd 5 will express it as 7.94 -5, giving you the [H+] concentration.
