I keep getting syntax error on my casio fx-991-ms calculator every time I try to divide a number by root 3 what am I doing wrong? For eg 208/square root 3 say for an electrical question.

The "syntax error" message that you are seeing on your Casio fx-991EX ClassWiz calculator is likely caused by the fact that the calculator does not support the use of decimal values in the exponent. The calculator can only accept integers (whole numbers) as exponents.
To work around this issue, you can try rounding the decimal value of the exponent to the nearest whole number. For example, if you need to calculate 1x10^7.2, you can round the exponent to 8 and calculate 1x10^8 instead. This will give you a close approximation of the desired result.
Alternatively, you can use a different calculator or software that does support the use of decimal values in the exponent. This will allow you to calculate the value more accurately.
If, for example, you're getting the square root of 3 as the square root of 3, press the S-D button (just above the DEL) button to convert the symbolic result to a decimal result.
If you want all results to come up in decimal, press SHIFT SETUP 2 to select the LineIO mode.
The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver. You cannot use it to solve equations. Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991. Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.
Press right-arrow when you're done with the argument of the square root. For example, from page E-15 of the manual, to calculate 1 + square_root(2) + 3, press 1 + square_root 2 right-arrow + 3 =
3.28 squared is 10.7584 . 10.7584 times 40 is 430.336 . It appears your calculator is correct. I get the same result on multiple calculators, as well as by hand.
Let's work this backwards: 431.8 divided by 40 is 10.795 . The square root of 10.795 is about 3.28557 .
To calculate a square root you press the square root key. A radical will be displayed. You type in the positive number whose root you want. Press the EXE key.
How about recreating the error and reporting faithfully the error message? You get a syntax error if you try to invert a matrix by using the wrong key sequence such a [SHIFT][MATRIX][3:MatA][X to ] -1), meaning that you use the universal power key on the same row as X squared and log and between them. To calculate the inverse of a matrix, have the name of the matrix on the command line, (see above) then press [X to -1] key one row up from [log].
Concerning your implied affirmation that if the matrix is square you should not be getting any error: You will get an error ( a Math error) if determinant of the matrix is equal to zero.
