Linear Algebra, scalars to find det(A)

1. The problem statement, all variables and given/known data

Let X1, X2,.....,Xn be scalars. Calculate det(A) where

A= nxn matrix with [ x1+1 x1+2......x1+n

x2+1 x2+2......x2+n

.... .... .....

xn+1 xn+2......xn+n]







2. Relevant equations

det(A) = (aij)(-1)^(i+j)det(aij)







3. The attempt at a solution



I have no clue how to even begin solving this problem I tried using above formula to no avail.

Please help!
