Consider the given that,
E={x|x={−3}n,x∈N,n<5.n∈N}
Hence, the set
E={(−3)1,(−3)2,(−3)3,(−3)4wheren<5,n<N}
E={−3,9,−27,81}
State, whether the following pairs of sets are equal or not:
(i) A={2,4,6,8} and B={2n:n∈N and n<5}
(ii) M={x:x∈ W and x+3 <8} and N={y:y=2n−1, n∈ N and n<5}
(iii) E={x:x2+8x−9=0} and F={1,−9}
(iv) A={x:x∈,x<3 } andB={y:y2−3y+2=0} Two sets are equal, if both the sets have same (identical) elements.
