Use the "x-superscript-box" key just below and right of the big circular cursor pad. It's the key between the x^2 and log keys.

SOURCE: entering denominator into casio fx-115ES calculator

Yeah use bracket sign if it in double enclosed use two open parenthesis and close on the other other side. Usually it is max it in triple parenthesis or bracket.

Example

((2x-2)-(2x+4)) { = usually means you gonna use three parenthesis or bracket ((( ))).

[ = means (( ))

( = means single ( ).

Goodluck.

Type solve(log(x^5,16)-log(125,64)+log(x^(1/2),4),x,0.5
Its equation with guess 0,5. Then press enter and you will give result
x=5^(1/3)=1.70997

On the TI83 calculator the equation solver dont workequation solver dont work


Most probable that you are not using the correct syntax.
Press MATH, then scroll down to reach the SOLVER line. Press ENTER. Create the equation, using the ALPHA keyboard to type in letter symbols.
Press ENTER. The screen that opens displays the equation and a list of the variable present in your equation. Each letter (variable) must have a value, except the unknown. If there is a 0 after the = sign on the same line as the unknown, you must clear it so as to leave a blank.
Specify the lower bound and the upper bound to speed up the search.
Once finished press [ALPHA][ENTER] to execute the (SOLVER)

Solve for x: x/3-1/5=4/3


Press [math] [0] to put the calculator into equation solver. Then you input your equation in 0 = format. So, the equation x/3 - 1/5 = 4/3 would be input as 0 = x/3 - 1/5 - 4/3 . Then press [enter] .

If you wan to solve an equation using the SOLVE feature you enter it as follows (your example)
You should rewrite it as 5/4*X-18+3 (= 0). Implicitly, the calculator assumes that the right side is ZERO and you do not enter any right side nor an equal sign.
Type in
5/4 [*] [X,T,theta, n] -18 +3 [ALPHA] [ENTER] (SOLVE)
You should get an answer -780/47 or the decimal equivalent (depending on display mode.)
