4.

  A   B    A XOR B   A' XOR B   A' XOR B'   (A XOR B)'

  0   0       0          1          0           1

  0   1       1          0          1           0

  1   0       1          0          1           0

  1   1       0          1          0           1

From the truth-table:

  A' XOR B  == (A XOR B)'

  A' XOR B' ==  A XOR B
