To raise e to the xth power, use e^x, which is the second function of the LN key to the left of the 4 key.

To enter a decimal exponent, use EE, which is the second function of the , key above the 7 key.

To raise a value to another value, use the ^ key, above the divide key.

Also, don't forget to use (-) instead of - when entering a negative exponent (or any other negative value).

Dividing 2 different scientic equations into another

Sorry but you are using the word EQUATION incorrectly. All you have is two numbers you want to divide one by the other.
Enter the numerator 1EE (-) 14, press the division key / then enter the 5 EE (-) 12. Press the = sign.
Note: to enter the negative sign in the exponents, use the change sign key marked (-), (+/-) or [+/-] . Do not use the regular MINUS sign.
When you use the EE key, you must not enter the 10. It is understood because EE is a shortcut for *10^.

I am changing something from grams to moles using Avogadro's number. When i put it into the calculator, I get the wrong answer. I have set up the problem correctly and I have an answer key. Do i need to...

Why not tell us what you are trying to do?.
n= number of moles
m= mass in g.
M= atomic or molar mass (in g/mol)
n=m/M (in mol)
To enter Avogadro's number you use the EE (*10^x) or Exp
6.02 [EE]23 No 10 should appear.
To calculate the atomic/molar mass use the Periodic table.

Does it refuse to do so or does it give an error message?
Three common errors:
  1. Not having the correct angle unit. Wrong result, No error message
  2. Confusing reciprocal of sine (1/sin(x) with arc sine (x) ,sin^-1(x). Confusing the reciprocal of cosine, 1/cos(x) with arc cosine (cos^-1(x)). Wrong result, No error message
  3. Taking the argument of the inverse sine and/or inverse cosine functions outside the interval [-1,1]. This gives a domain error.

3000 - 4565.72
