यदि \(9^2-4^2\) को दृश्य मॉडल से हल करें, तो कौन सा आयत बनेगा?
If \(9^2-4^2\) is solved using a visual model, which rectangle is formed?
Explanation opens after your attempt
A. आयाम \(9+4\) और \(9-4\)Dimensions \(9+4\) and \(9-4\)
Concept
In difference of squares, dimensions become \((a+b)\) and \((a-b)\). Exam tip: compute \(9^2-4^2=(13)(5)\).
Why this answer is correct
The correct answer is A. आयाम \(9+4\) और \(9-4\) / Dimensions \(9+4\) and \(9-4\). In difference of squares, dimensions become \((a+b)\) and \((a-b)\). Exam tip: compute \(9^2-4^2=(13)(5)\).
Exam Tip
अंतर के वर्गों में आयाम \((a+b)\) और \((a-b)\) बनते हैं। परीक्षा में \(9^2-4^2=(13)(5)\) करें।
