A=(1,2,5) B=(6,7) X is the universal set for A and B (X=(1,2,3...10) B'=(1,2,3,4,5,6,7,8,9,10) From LHS side (1,2,3) intersection (1,2,3,4,5,6,7,8,9,10) (1,2,5)(which is equal to A) Hence it is proved

A=(1,2,5)
B=(6,7)
X is the universal set for A and B { X =(1,2,3,4...10)} B'={1,2,3,4,5,8,9,10}
from LHS side
{1,2,5} intersection{1,2,3,4,5,8,9,10}
{1,2,5} (which is equal to A)
Hence it is proved
