यदि \(A={x:x=2k,\ k\in\mathbb{Z}}\) और \(B={x:x=4k,\ k\in\mathbb{Z}}\), तो सही संबंध कौन-सा है?
If \(A={x:x=2k,\ k\in\mathbb{Z}}\) and \(B={x:x=4k,\ k\in\mathbb{Z}}\), which relation is correct?
Explanation opens after your attempt
Correct Answer
A. \(B\subseteq A\)
Concept
Every multiple of (4) is also a multiple of (2). Therefore \(B\subseteq A\).
Why this answer is correct
The correct answer is A. \(B\subseteq A\). Every multiple of (4) is also a multiple of (2). Therefore \(B\subseteq A\).
Exam Tip
हर (4) का गुणज (2) का भी गुणज होता है। इसलिए \(B\subseteq A\) है।
