SOURCE: TI-15 square root Function

Hello,
You should enter it as follows [SQRT]36 ) [ENTER/=].
If you define some function f of a variable x you write that f(x), where the parentheses enclose the so-called argument (objet on wich the function acts). It seems that on this calculator the opening parenthesis is implicit: the calculator supplies it when you press [SQRT] but does not display it (a design flaw?). However the closing parenthesis must be entered by you to signifie to the function [SQRT] that you have finished entering the argument. Weird but one can live with it.
Hope it helps.

Press the MATH key to bring up the Math menu. Option 3 gives you cubed, option 4 gives you cube root, option 5 gives you nth root.

For example, 3rd root of 8: MATH 4 8 ENTER gives 2.

4th root of 16: 4 MATH 5 16 ENTER gives 2.

2nd [square-root] 9 ) =

The square-root is the shifted function of the x-squared key, just to the left of the 7 key. The close-parenthesis is needed to balance the open-parenthesis automatically inserted by the square-root function.

There are limits to what the calculator can display in symbolic form, and roots beyond the second (square roots) are beyond its capabilities. Even something as simple as the cube root of 2 will be displayed numerically.

### How to use the exponent key on a casio fx 300ES calculator ?

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][=]
