Use the (-) key in the leftmost column above the RCL key to enter negative values, not just powers.

SOURCE: How to use negative exponents on a calculator?

your calculator will never allow you to enter a negative exponent. so heres what you do.Any negative exponent of a number can be reversed and turned into a fraction for example 4^-1=1/4 or 8^-2=2/8=0.25. Hope this helps.

When I square a negative number, my calculator gives me a negative number. i.e. -4^2=-16


No, you're not squaring a negative number, you're negating a square. When you press (-) 4 ^ 2 ENTER , the calculator is calculating -(4^2). 4^2 is 16, and the negative of that is -16. What you want to do is to calculate (-4)^2 by pressing ( (-) 4 ) ^ 2 ENTER .

TI-84 Plus Silver Edition. When dividing negative powers of ten by other negative powers of 10 the calculator it just adds the the negative powers together. How do i fix this? An example: 5*10^-10 /...


To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating
5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

Negative log


Use the log function (common logarithm). See screen capture for markings on key.
83c0b62.jpg
To evaluate the negative of a logarithm
Enter the number (argument) of the logarithm
Press the = key to have it calculated.
While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation
log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.
[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.
[)] is the enclosing right parenthesis
[+/-] is the Sign Change key

Needing help with addint the power of into calculator


Use the key labeled times 10 to power X, the one between the decimal dot ant the Ans keys, in the middle of the bottom row of keys.
10 to the power 0 is entered as 1. [x10^X] 9 or simply [x10^X] 9
To enter negative exponents use the change sign key [(-)] just above the [RCL] key
10 to -9 is entered as [x10^X] [(-)] 9 result is shown as 1x10-9.

I am tutoring a student who uses the Casio fx-300MS. A problem required that he raise (-2) to the 4th power, and the calculator indicated the answer was -16. I know that the answer should be a positive 16,...


Enclose any negative number between parentheses before squaring.
If you enter -4^2, where - is the negation, the result will be -16 because of the priority rules: exponentiation (power) has priority over negation.
If you enter (-4)^2 the result will be 16, because parentheses have priority over the squaring: the 4 is negated then the result is squared.

When I enter -5^2 I keep getting -25. Same for when I enter -5 and push the squared button. What is wrong?


Hello,
What you are calculating is -1 times 5^2 which is -1*25=-25.
If you want to calculate the square of -5 you enclose it between parentheses.

Reason

There are two operations: the power and the negation and the power has priority. Thus 5^2 is calculated first, then its negative is taken.
If you put it inside parentheses, the () has priority. The negative of 5 is taken first, then the result is squared giving 25.

(-5)^2=25.
Hope it helps.

To the power of a negative


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.

Negitive powers


Use the ^ key to insert a power (it's located above the division key) then put a negative power by typing the negative key (located at the very bottom right of the keypad next to the ENTER key) and then the number of the power.

10^-3

If this doesn't give the right result, put the negative power in parentheses. I can't remember off hand if you need to do that or not.

10^(-3)

Casio calculator fc-100v, to the power of?


Hello

To calculate a number to an arbitrary power you use the button labeled ^ .

If you want the cube of 2 your enter
[2][^][3] will give you 8. If your exponent is negative use the sign change key (-) and close the negative exponent between parentheses : for exemple the sequence to compute 2 to power of negative 5 is as follows
2[^] [(] 5 [(-)] [)] which means you enter the value of the exponent before the change sign (-). If you use the big MINUS sign you will get a syntax error.

Hope it helps.
