यदि \(A=\{0,1\}\) और \(B={x:x^2=x}\), तो सही संबंध क्या है?
If \(A=\{0,1\}\) and \(B={x:x^2=x}\), what is the correct relation?
Explanation opens after your attempt
Correct Answer
A. (A=B)
Concept
From \(x^2=x\), (x(x-1)=0), so (x=0) or (x=1). Both sets are equal.
Why this answer is correct
The correct answer is A. (A=B). From \(x^2=x\), (x(x-1)=0), so (x=0) or (x=1). Both sets are equal.
Exam Tip
\(x^2=x\) से (x(x-1)=0), इसलिए (x=0) या (x=1)। दोनों समुच्चय समान हैं।
