Answer 1

Answer:

a. A={31,21,53}

B={x:x=n+2n,n∈N}

B={31,42,53…}

A=B , So A and B are not equivalent

b. A={a,b,c…z} and B={26,25,24…3,2,1}

Here, the numbers are in reverse order of alphabets. ∴ A and B are equivalent

 

c.   B={x:x=n3+1n3−1n∈W,n≥3}

A={1413,6563,6362}

B={0,97,1413}                                       

A=B. So A and B are not equivalent

 

d.  A={2,4,
