Question

Give an equal and an equivalent set for the following Y = {x:x=3n,n​

Answer 1

Answer:

Equal sets:

The two given sets are called Equal Sets if their number of elements and the member of elements are exactly same.

A={x:x∈N,x<3}={1,2}

B={1,2}

C={3,1}

D={x:x∈N,x is odd,x<5)={1,3}

E={1,2,1,1}={1,2}

F={1,1,3}={1,3}

Hence equal sets are:

A=B=E,C=D=F

A=B=E,C=D=F
