For (A+B)^n, compute them for n=2,3,4,... to see what is going on or just use the binomial theorem.
X = [1 1]
Y = [1 -1]
Let A = aX and B= bY, where a and b are constants.
Use different values of a and b to calculate A^2, A^3, A^4 ...., B^2, B^3...
By consedering integer powers of A and B, find expression for A^n, B^n , (A+B)^n
Please help me to figure out this problem!! thanks in advance..
