यदि \(A=\{1,2,3,4\}\) पर \(R=\{(a,b):a+b=5\}\), तो \(R\circ R\) किसके बराबर है?
If \(R=\{(a,b):a+b=5\}\) on \(A=\{1,2,3,4\}\), what is \(R\circ R\) equal to?
Explanation opens after your attempt
Correct Answer
A. \(I_A\)
Concept
This relation sends each (a) to (5-a), and applying it twice returns (a) to itself. Therefore \(R\circ R=I_A\).
Why this answer is correct
The correct answer is A. \(I_A\). This relation sends each (a) to (5-a), and applying it twice returns (a) to itself. Therefore \(R\circ R=I_A\).
Exam Tip
यह संबंध हर (a) को (5-a) से जोड़ता है, और दो बार लगाने पर (a) फिर (a) पर लौटता है। इसलिए \(R\circ R=I_A\) है।
