( 1 9 / 8 ) y^x ( 1 / 7 2 0 ) =

The same way you raise a number to a non-fractional power, using the y^x button. For your example, press

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

3 y^x ( 1 / 1 2 ) =

or

3 y^x 1 2 1/x =

Which exponent function?

To enter an exponent of ten, use 2nd [EE].

To raise ten to an exponent, use 2nd [10^x].

To raise e to an exponent, use 2nd [e^x].

To raise an arbitrary number to an exponent, use ^.

For negative numbers (not just exponents), make sure you use the (-) key just to the right of the decimal point key, not the - key for subtraction.

For what follows I'm going to assume you have at least version 2.53 of the operating system for the 84Plus. If you have an older version, I STRONGLY recommend you update it:

You can use the "n/d" command in the MATH/NUM menu to enter the division bar. For example, to enter 1/2, press 1 MATH right-arrow ALPHA [D] 2 ENTER. If you just want the number, you can also enter it as 1 / 2.

You can convert a decimal number to a fraction using the >Frac command in the MATH menu. For example, to convert 0.2 to a fraction, press . 2 MATH 1 ENTER.

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)

Use the general power key marked with X to the y ( look for the image of a key on same line as Power in the screen capture)

You enter a number then press the power key and finally the exponent. If exponent is complicated (fraction, negative or other) enclose the exponent in parentheses.

You aslo have dedicated keys for certain powers and roots (square, square rooot, cube, cubic root)

The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).

- You enter the base (the number to be raised to a power).
- You press the [X to ] power key.
- You close the parenthesis (the right one).
- You press [=]

Hello,

You have the [X to the 3] for the cube and the [Y to the x] for any exponent: (positive, negative, or a fraction).

Hope it helps.

Uh yes it will allow you to enter a negative exponent.... press the numbers you want then hit EXP button, then hit the +/- button and then the exponent. 60 % of the time, it works...... everytime.

Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH

Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.
