Hello,
The calculator applies the rules during the internal calculations. But all it shows you is the (final) result. It does not keep track of what exponents you used to get to the result. It is not capable of doing symbolic manipulations.
Hope you are not too disappointed.

Hi,
First let us repair the terminology.

1. You can evaluate any expression (find the value of any expression for a particular value of its variable).Store a value in the variable, say X. Key in the expression and press [EXE].
2. You can consider your expression(should not contain a relational operator such as =, greater than, less than, greater than or equal to, less than or equal to) to be a function Y1(x) = expression and graph it, or generate a table for it. You will have several values of the function calculated at various points.
3. You can set your expression equal to 0 and find the particular value(s) of the variable (the unknown) that make the equality TRUE. That is called solving an equation.
I am not sure that it has a solver (solving an equation or an inequation) but you can always draw your expression as a function and explore the graph (SKTCH) to locate the roots (or zeros) of the functions (the values of the variable where the function equals zero.) That is called solving graphically.

Hope it helps.
Thank you for using FixYa and for rating this solution.

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).

1. You enter the base (the number to be raised to a power).
2. You press the [X to ] power key.
3. You close the parenthesis (the right one).
4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]

It is the [xy] key.

What you call the EE ((entering power of 10 exponents) is done with the help of the key at the bottom right, and marked [x10^X].
To enter 6.02x10^23, you do as follows
6.02 [x10^X]23. When you use that short-cut key, no 10 should appear on the command line. See screen capture. Sep 08, 2014 | Casio fx-115ES Plus Scientific Calculator

### Resetting casio FX-115W

Casio fx-115W was locked into some sort of mixed-up engineering output but without the exponent. There is no reset method to my knowledge but by removing the battery and putting the calculator in a drawer for 30 minutes then re-installing the battery the calculator reset to default values and works properly.

You can set the number display mode to be SCI. Press [SHIF][MODE] and look for the number to the right of which is written SCI. Enter that number. You may be asked to specify the number of digits after the decimal mark 0 tilda 9. Select an appropriate number and enter the corresponding key.
If you want to ENTER numbers in scientific format, enter them the usual way. When you arrive to the power of 10 press the [x 10^X] key, followed by the exponent. Use the change sign key (-) to enter a negative exponent.

### Im trying to graph a parametric equation and whenever the equation has an exponent/power in it the calculator says Syn error so i know how to graph x=2 cos T, y=2 sin T and similar equations without a...

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).
As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

### Where is the exponent key on Casio fx-115es calculator?

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.

### Exponents on Casio fx-115MS

Hello
Use the general power key labelled as [^], or [X to the y] or [Y to the x] depending on calculator.
3500000 [ / ] [(]7.5 [^] 20[)] [=] gives 1.103678993 E -11
Hope it helps.
