कौन-सा विकल्प \(\sqrt{2}+\sqrt{3}+\sqrt{6}\) के परिमेय होने के दावे को गलत दिखाने में मदद करता है?

Which option helps show that the claim \(\sqrt{2}+\sqrt{3}+\sqrt{6}\) is rational is false?

Correct Answer

A. विभिन्न अपूर्ण वर्गों के मूल स्वतंत्र अपरिमेय भाग देते हैंRoots of different non-perfect squares give independent irrational parts

Step 1

Concept

\(\sqrt{2}\), \(\sqrt{3}\), and \(\sqrt{6}\) are linked to different non-perfect squares.

Step 2

Why this answer is correct

Their irrational parts do not cancel through ordinary addition, so the sum is not rational.

Step 3

Exam Tip

Avoid false identities such as \(\sqrt{a+b}=\sqrt{a}+\sqrt{b}\). चरण 1: \(\sqrt{2}\), \(\sqrt{3}\), और \(\sqrt{6}\) अलग-अलग अपूर्ण वर्गों से जुड़े हैं। चरण 2: इनके अपरिमेय भाग सामान्य जोड़ से पूरी तरह नहीं कटते, इसलिए योग परिमेय नहीं बनता। चरण 3: ऐसे दावों में गलत पहचान जैसे \(\sqrt{a+b}=\sqrt{a}+\sqrt{b}\) से बचें।
