यदि किसी वर्ग मॉडल में \(x^2\) और (64) कोने के वर्ग हैं, तो पूर्ण वर्ग बनने के लिए बीच का संयुक्त पद क्या होना चाहिए?
If a square model has corner squares \(x^2\) and (64), what combined middle term is needed to form a perfect square?
Explanation opens after your attempt
B. (16x)
Concept
Since \(64=8^2\), the combined middle term is \(2\cdot x\cdot 8=16x\). Exam tip: get side (8) from the corner square.
Why this answer is correct
The correct answer is B. (16x). Since \(64=8^2\), the combined middle term is \(2\cdot x\cdot 8=16x\). Exam tip: get side (8) from the corner square.
Exam Tip
\(64=8^2\) है इसलिए संयुक्त मध्य पद \(2\cdot x\cdot 8=16x\) होगा। परीक्षा में कोने के वर्ग से भुजा (8) निकालें।
