i obtained an equation which i simplified further to some extent but after simplification i am not getting the required output which i was getting before(without simplification)...

Function:

AD'+BC'D+A'B'CD

my simplification:

AD'+(BC'+A'B'C)D

AD'+[(BC'+A')(BC'+B'C)]D (Distribution)

AD'+(BC'+A')(B XOR C)D

Is it fine n max simplified..??

help will highly b appreciated
