I need help with this CRYPTOGRAPHY problem, I cannot figure it out and need help revising.

3. Suppose the key for round 0 in AES consists of 128 bits, each of which is 1. Show that the key for the first round is (W (4), W (5), W (6), W(7)), where 00010111 00010110 W (4) = W(6) = 00010110 00010110 11101000 W (5) = W(7 ) = 11101001 11101001 11101001
