Use the (-) key just to the right of the decimal point, not the - key. The second key is for subtraction.

Use the (-) key (just to the right of the decimal point key) instead of the - key when entering a negative number (not just exponents).

- is used to subtract one value from another. (-) is used to negate a value. - operates on two numbers, (-) operates on one.

Be sure to use the (-) negative key and not the - minus key.

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.

Use the universal power key marked [Y to x] or [Y^x].

This key allows you to calculate powers with arbitrary exponents.

To obtain the roots to any degree you make use of the fact that n-th root of a number X is equivalent to the number X raised to the power 1/n

10th root of X = X raised to the power 1/10

10 th root of 2345 = (2345)^ (0.1)

For this case

2345^(0.1)=2.172772644

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).

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)

Having gone over a month with no response, I assume this is no longer a problem.

I think you are using the minus symbol instead of the negative symbol (located below the 3).
