Looking at the decimal only gives an idea.

Step 2

Why this answer is correct

A complete proof assumes rationality and shows the common-factor contradiction.

Step 3

Exam Tip

In exams, write a proof, not a guess. चरण 1: दशमलव को देखकर केवल अनुमान बनता है। चरण 2: पूर्ण प्रमाण में परिमेय मानकर साझा गुणनखंड का विरोधाभास दिखाते हैं। चरण 3: परीक्षा में अनुमान नहीं, प्रमाण लिखें।
