वर्गमूल सर्पिल में \( \sqrt{18} \) बनाने के ठीक पहले कौन-सा कर्ण बन चुका होता है?
In the square root spiral, which hypotenuse is already formed just before constructing \( \sqrt{18} \)?
Explanation opens after your attempt
Correct Answer
A. \( \sqrt{17} \)
Concept
\( \sqrt{18} \) is formed by adding a perpendicular (1) to the previous hypotenuse \( \sqrt{17} \). Always check the previous square root in the sequence.
Why this answer is correct
The correct answer is A. \( \sqrt{17} \). \( \sqrt{18} \) is formed by adding a perpendicular (1) to the previous hypotenuse \( \sqrt{17} \). Always check the previous square root in the sequence.
Exam Tip
\( \sqrt{18} \) पिछले कर्ण \( \sqrt{17} \) पर (1) लंबवत जोड़कर बनता है। क्रम में हमेशा पिछले वर्गमूल को देखें।
