Question

A = {x : x is a prime factor of 40} B = {x:x is a divisor of 10} Is a subset to b or b subset to a

Answer 1

Answer:

A = {x : x is a prime factor of 40} = { 2, 5}

B = {x:x is a divisor of 10} = { 1, 2, 5}

So every element of A is an element of B but not the converse

So A is a subset of B
