If E is the universal set and `A=BuuC`, then the set `E-(E-(E-(E-(E-A))))` is same as the set

If E is the set of equilateral triangle and I is the net of isoscales triangle then find I - E

Let U= {a,b,c,d,e,f,g} be the universal set and let its subsets be A = {a,b,d,e} and B = {b,e,g} Verify that : ( Auu B )' = ( A' nn B ')

Let U= {a,b,c,d,e,f,g} be the universal set and let its subsets be A = {a,b,d,e} and B = {b,e,g} Verify that : ( A nn B) ' = ( A' uu B')

If R is the set of Positive rational number and E is the set of real numbers,then

If A = {a, b, c} and B = {b, c, d, e} be two subsets of the universal set U = { a, b, c, d, e} , then ( A cup B) ' is equal to

If A = phi , then the number elements in P(A), (i.e., the number of elements in the power set of A) is
