What about the "Exp" key just above the "7" key? This key will let you enter an exponent of 10 when entering a number.

It depends on the base of the power function.

**For exponential function** use [SHIFT][LN] (e^x) followed by the exponent value. If exponent is negative use the change sign +/- key before exponent.

For a**general power**, type in the base (number), then press the [Y^x] key followed by the exponent.

For a**power of 10,** use the [Exp] key. Careful here. For example to enter 1.6x10^(-19), type in 1.6, press the [Exp] key, then the change sign key +/- and the exponent. Press [=]

**1 . 6 [Exp] +/- 19 [=]**

The key you are looking for looks like y raised to the exponent x. It is below the "hyp" key. To determine an exponent, enter you base, hit the y to the x key and enter the exponent.

For example, 3 to the power of 4, enter 3, hit the y to the x key, and enter 4 and hit the = key.

Good luck.

To enter exponents (1, 2, 3, -3..) use the general power key marked with Y^x or X^y or ^. Enter the base press the general power key then the exponent. If exponent is negative try enclosing it in parentheses. use the change sign key (-) to enter the negative sign before the exponent.

To enter power of 10, you can use the shortcut key marked Exp (the 10 must not appear when the Exp is used to enter exponents for power of 10).

If you mean the key to raise a number to an exponent, it's the key marked "y^x", two keys above the "7" key. If you mean the key to enter an exponent of ten, it's the key marked "Exp", just above the "7" key.

To enter exponents of an arbitrary base, use the key that is marked [Y^x]

To enter exponent of 10 press the [EE] key. In scientific notation display, the exponent of the power of 10 is displayed to the right of the mantissa.

To raise 10 to an exponent, use the 10^x function (SHIFT log). To raise e to an exponent, use the e^x function (SHIFT ln). To raise an arbitrary value to an exponent, use x^y (just above the sin key). To enter an exponent of ten, use the x10^x key to the right of the decimal point.

Type in the mantissa, then the EE key (for Enter Exponent) above the 7 key, then the exponent. If it's a negative exponent, press the (-) key to the right of the decimal point before entering the exponent.

I don't know about this specific calculator, but there is probably a button on your calculator that has a "y" with an "x" as a superscript (exponent). Or is could be reversed. But you wanted 2^8, you would push the 2 first, then the exponent button, then the 8, and there's your answer.

Good luck.

To write 50 exponent in math mode, type your number then hit the key that has (x with the solid white exponent key). It's between the (x squared key) and the (log key) then you can enter the number 50 for your exponent. You can also hit the (x squared key) delete the 2 exponent and type in the exponent you want.
