What do we get after simplifying \(\sqrt{18}\)?
A. \(3\sqrt{2}\)
\(\sqrt{18}=\sqrt{9\times2}=3\sqrt{2}\) होता है। इसलिए \(\sqrt{18}\) अपरिमेय है। / \(\sqrt{18}=\sqrt{9\times2}=3\sqrt{2}\). Therefore \(\sqrt{18}\) is irrational.

Which is the simplified form of \(\sqrt{50}\)?
C. \(5\sqrt{2}\)
\(\sqrt{50}=\sqrt{25\times2}=5\sqrt{2}\) है। \(\sqrt{2}\) बचने से यह अपरिमेय है। / \(\sqrt{50}=\sqrt{25\times2}=5\sqrt{2}\). Since \(\sqrt{2}\) remains, it is irrational.

What type of number is \(1+\sqrt{2}\)?
B. अपरिमेयIrrational
\(\sqrt{2}\) अपरिमेय है इसलिए \(1+\sqrt{2}\) भी अपरिमेय है। परिमेय संख्या जोड़ने से अपरिमेय भाग खत्म नहीं होता। / \(\sqrt{2}\) is irrational so \(1+\sqrt{2}\) is also irrational. Adding a rational number does not remove the irrational part.

Which is an example of a non-terminating non-repeating decimal?
C. \(1.010010001\ldots\)
\(1.010010001\ldots\) में निश्चित दोहराव नहीं है। इसलिए यह अपरिमेय दशमलव का उदाहरण है। / \(1.010010001\ldots\) has no fixed repetition. So it is an example of an irrational decimal.

Which form is obtained after simplifying \(\sqrt{20}\)?
A. \(2\sqrt{5}\)
\(\sqrt{20}=\sqrt{4\times5}=2\sqrt{5}\) है। \(\sqrt{5}\) के कारण यह अपरिमेय है। / \(\sqrt{20}=\sqrt{4\times5}=2\sqrt{5}\). Because of \(\sqrt{5}\), it is irrational.

Between \(\sqrt{64}\) and \(\sqrt{65}\), which number is irrational?
B. \(\sqrt{65}\)
\(\sqrt{64}=8\) परिमेय है लेकिन (65) पूर्ण वर्ग नहीं है। इसलिए \(\sqrt{65}\) अपरिमेय है। / \(\sqrt{64}=8\) is rational but (65) is not a perfect square. Therefore \(\sqrt{65}\) is irrational.
