\(यदि (U={x:x \in \mathbb{Z}, -5 \le x \le 5}) और (A={x:x \in U\) तथा \(x^2<10}) है, तो (A') ज्ञात कीजिए\)।

\(If (U={x:x \in \mathbb{Z}, -5 \le x \le 5}) and (A={x:x \in U\) and \(x^2<10}), find (A').\)

Explanation opens after your attempt
Correct Answer

A. (A'={-5,-4,4,5})

Step 1

Concept

For \(x^2<10\), \(A=\{-3,-2,-1,0,1,2,3\}\). Removing these from (U) gives (A').

Step 2

Why this answer is correct

The correct answer is A. (A'={-5,-4,4,5}). For \(x^2<10\), \(A=\{-3,-2,-1,0,1,2,3\}\). Removing these from (U) gives (A').

Step 3

Exam Tip

\(x^2<10\) के लिए \(A=\{-3,-2,-1,0,1,2,3\}\) होगा। इसलिए (U) से इनको हटाने पर (A') मिलता है।
