वर्गमूल सर्पिल में यदि पिछला कर्ण \(\sqrt{18}\) है, तो (1) इकाई लंब जोड़ने पर नया कर्ण किस गणना से मिलेगा?
In a square root spiral, if the previous hypotenuse is \(\sqrt{18}\), by which calculation will the new hypotenuse be obtained?
Explanation opens after your attempt
A. \(\sqrt{18+1}\)
Concept
The correct hypotenuse is (\sqrt{\(\sqrt{18}\)2+12}=\sqrt{19}). In a square root spiral, the number increases by (1) at each step.
Why this answer is correct
The correct answer is A. \(\sqrt{18+1}\). The correct hypotenuse is (\sqrt{\(\sqrt{18}\)2+12}=\sqrt{19}). In a square root spiral, the number increases by (1) at each step.
Exam Tip
सही कर्ण (\sqrt{\(\sqrt{18}\)2+12}=\sqrt{19}) होगा। वर्गमूल सर्पिल में हर चरण में संख्या (1) बढ़ती है।
