वर्गमूल सर्पिल में यदि पिछले कर्ण की लंबाई \(\sqrt{80}\) है और नई लंब (1) इकाई है, तो नया कर्ण किस सटीक मान पर स्थित होगा?
In a square root spiral, if the previous hypotenuse is \(\sqrt{80}\) and the new perpendicular is (1) unit, at what exact value will the new hypotenuse lie?
Explanation opens after your attempt
A. \(\sqrt{81}=9\)
Concept
The new hypotenuse is \(\sqrt{80+1}=\sqrt{81}\). Since \(\sqrt{81}=9\), write the exact value at a perfect square.
Why this answer is correct
The correct answer is A. \(\sqrt{81}=9\). The new hypotenuse is \(\sqrt{80+1}=\sqrt{81}\). Since \(\sqrt{81}=9\), write the exact value at a perfect square.
Exam Tip
नया कर्ण \(\sqrt{80+1}=\sqrt{81}\) होगा। \(\sqrt{81}=9\), इसलिए पूर्ण वर्ग पर सटीक मान लिखें।
