वर्गमूल सर्पिल में यदि किसी चरण पर कर्ण \(\sqrt{728}\) है, तो अगले कर्ण को संख्या रेखा पर रखने से पहले कौन-सा अंतराल सही होगा?
In a square root spiral, if the hypotenuse at a step is \(\sqrt{728}\), which interval is correct before placing the next hypotenuse on the number line?
Explanation opens after your attempt
C. \(\sqrt{729}=27\)
Concept
The next hypotenuse is \(\sqrt{728+1}=\sqrt{729}\). Since \(729=27^2\), it will lie exactly at (27).
Why this answer is correct
The correct answer is C. \(\sqrt{729}=27\). The next hypotenuse is \(\sqrt{728+1}=\sqrt{729}\). Since \(729=27^2\), it will lie exactly at (27).
Exam Tip
अगला कर्ण \(\sqrt{728+1}=\sqrt{729}\) होगा। \(729=27^2\), इसलिए यह ठीक (27) पर स्थित होगा।
