कौन-सा कथन \(\sqrt{3}\) के प्रमाण में गलत लेकिन आकर्षक उत्तर हो सकता है?

Which statement can be a wrong but tempting answer in the proof of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

A. \(p^2=3q^2\) से (p=3q)From \(p^2=3q^2\), (p=3q)

Step 1

Concept

A square relation does not directly give a linear relation. The correct logic is \(3\mid p^2\Rightarrow3\mid p\).

Step 2

Why this answer is correct

The correct answer is A. \(p^2=3q^2\) से (p=3q) / From \(p^2=3q^2\), (p=3q). A square relation does not directly give a linear relation. The correct logic is \(3\mid p^2\Rightarrow3\mid p\).

Step 3

Exam Tip

वर्ग संबंध से सीधे रैखिक संबंध नहीं मिलता। सही तर्क \(3\mid p^2\Rightarrow3\mid p\) है।

कौन-सा कथन \(\sqrt{2}\) के प्रमाण में गलत लेकिन आकर्षक उत्तर हो सकता है?

Which statement can be a wrong but tempting answer in the proof of \(\sqrt{2}\)?

Explanation opens after your attempt
Correct Answer

C. \(a^2=2b^2\) से सीधे (a=2b) हैFrom \(a^2=2b^2\), directly (a=2b)

Step 1

Concept

This is a wrong shortcut while taking square roots. The correct reasoning uses parity.

Step 2

Why this answer is correct

The correct answer is C. \(a^2=2b^2\) से सीधे (a=2b) है / From \(a^2=2b^2\), directly (a=2b). This is a wrong shortcut while taking square roots. The correct reasoning uses parity.

Step 3

Exam Tip

यह वर्गमूल निकालने की गलत जल्दबाजी है। सही तर्क समता से चलता है।
