Sum of the First n Odd Natural Numbers Is Equal to n Squared

Let A = x suc...

Question

Let A = {x such that x belongs to N and x+1 < 8} and B = {x such that x belongs to N and x+3≤5}. Then find A union B?

Open in App

Solution

Really N means natural number .so
A={1,2,3,4,5,6}
B={1,2}

AUB ={1,2,3,4,5,6}=A.
It is because
B C A ie B subset of A.
