Not sure about the Casio, but most calculators which have capability to handle complex numbers should be similar. Input the complex number according to however you normally do that, then raise to a power. In the case of roots, you want to raise to a reciprocal power: Square root is 0.5 power, cube root is 1/3 power, fourth root is 0.25 power, etc
3 simple steps. i) press square root button ii) enter the number iii) hit "=" is it really that hard to figure out? ...... For complex numbers, refer to the definition of a complex number (abs(a)*exp(-j*angle(a)))1/2 = sqrt(abs(a))*exp(-j*angle(a)/2). therefore to do this on the casio fx-991ms try the following(assuming the complex number is stored in the ans): (sqrt(abs ans))[angle symbol]((arg ans)/2) added by Greg ......
To find the inverse of a matrix on a Casio fx-991MS scientific calculator, you first need to input the matrix you want to find the inverse of. Then, press the "SHIFT" button followed by the "MODE" button to access the matrix mode. Select the matrix you want to invert by pressing the corresponding number key. Next, press the "SHIFT" button followed by the "MATRIX" button, and then press the "x^-1" button to calculate the inverse of the matrix.
To do matrix multiplication in calculator Casio fx-991MS follow the steps below:- 1] Enter in the matrix mod:- press MODE 3 times then press 2. 2] To enter the matrix:- press SHIFT and then 4. press 1 to select Dim. to enter the matrix. Suppose u hv to multiply the matri A with matrix B then seletect A by pressing 1 chose dimension for matrix A let m=2 so press 2 then '=' again let n=2 so press 2 then '=' Now, enter the values in matrix MatA11, MatA12, MatA21,MatA22 every time enter the value and then ' =' to enter another values.. remember values get stored in the sequence of row mean 11,21,21,22 now u feel all the values of Matrix A now to enter value of matrix B press SHIFT and again 4. seect Dim by pressing 1. this time chose Mat B and follow the steps same as u use to feel values in matrix A. after entering the values. u stored matrix A and B. 3]Now multiply Matrix A and Matrix B:- press again Shift then 4 and this time select option Mat by pressing 3 to multiply matrix A and matrix B press 1(select Mat A) then press Multiply operator(*/cross). again press Shift then 4 then press 3 and nw selec/press 2(select Mat B) then press '=' 4] you will get the another matrix Ans But the values are in the sequence of row to see next vaues in that matrix press '>' side of REPLAY button.

It's impossible
To find the determinant of a matrix on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Then, navigate to the matrix menu and select the matrix you want to find the determinant of. Finally, choose the option to calculate the determinant, and the calculator will display the result. Remember that the determinant of a matrix is a scalar value that represents certain properties of the matrix.

Afaik it can do summation only in statistic- and regression operation-mode, where you put in x, or, x y sample data from 0 to n samples. There it is possible to create a modified summation formula on these data variables.
To perform matrix calculations on a Casio fx-991MS calculator, you first need to enter the matrix into the calculator using the matrix mode. Press the "Mode" button, then select "Matrix" mode by pressing the corresponding number key. Next, input the dimensions of the matrix (rows and columns) and enter the values of the matrix. Once the matrix is entered, you can perform operations such as addition, subtraction, multiplication, and finding the determinant or inverse using the matrix menu options.
mode--->SD(select by pressing 1) Shift mode(CLR) and again 1 to erase any previous statistical Data(SCL) input the relevent data n press M+ on each interval..then after addin all the data Shift 2 SD can be taken using either pressing 2(for over 30 data) or 3(for less than 30 data)
