Which statement about \(\sqrt{121}\) and \(\sqrt{122}\) in a square root spiral is correct?
Explanation opens after your attempt
A. \(\sqrt{121}=11\) और \(\sqrt{122}\) अपरिमेय है\(\sqrt{121}=11\) and \(\sqrt{122}\) is irrational
Concept
(121) is a perfect square, but (122) is not. Therefore \(\sqrt{122}\) is irrational.
Why this answer is correct
The correct answer is A. \(\sqrt{121}=11\) और \(\sqrt{122}\) अपरिमेय है / \(\sqrt{121}=11\) and \(\sqrt{122}\) is irrational. (121) is a perfect square, but (122) is not. Therefore \(\sqrt{122}\) is irrational.
Exam Tip
(121) पूर्ण वर्ग है, लेकिन (122) पूर्ण वर्ग नहीं है। इसलिए \(\sqrt{122}\) अपरिमेय है।
