यदि (-3<x<-1) है, तो \(x^2\) के लिए कौन सा कथन सही है?
If (-3<x<-1), which statement about \(x^2\) is correct?
Explanation opens after your attempt
A. \(1<x^2<9\)
Concept
On this interval, (|x|) lies between (1) and (3), so \(1<x^2<9\). For squares on negative intervals, look at magnitude.
Why this answer is correct
The correct answer is A. \(1<x^2<9\). On this interval, (|x|) lies between (1) and (3), so \(1<x^2<9\). For squares on negative intervals, look at magnitude.
Exam Tip
इस अंतराल में (|x|) (1) और (3) के बीच है, इसलिए \(1<x^2<9\)। ऋणात्मक अंतराल में वर्ग के लिए परिमाण देखें।
