Question: How to compute direct exponentiation of the matrix

Hi EveryOne!

In the the answer of the question "How to find k^th root of the given matrix over finite field (at URL: Carl Love helped to find k^th root of the given matrix M over GF(2m)/f(x).

Now, I need to compute direct exponentiation of the given matrix M in finite field. (If M = [mi,j], we say Direct Exponent (element-wise exponent matrix), Mdk of M is a matrix whose each element is the result of exponentiation of corresponding elements of M. If k=2, then we say Md2 is a direct square matrix of M )

Please help me!!! Thank you very much.
