Correct Answer

A. परिमेय मानकर उसी अभाज्य गुणनखंड को अंश और हर दोनों में दिखानाAssume rational and show the same prime factor in both numerator and denominator

Step 1

Concept

Factor (3) works in \(\sqrt{3}\) and factor (5) works in \(\sqrt{5}\).

Step 2

Why this answer is correct

The rational assumption makes that same factor appear in both numerator and denominator.

Step 3

Exam Tip

This common factor contradicts lowest form. चरण 1: \(\sqrt{3}\) में गुणनखंड (3) और \(\sqrt{5}\) में गुणनखंड (5) काम करता है। चरण 2: परिमेय मान्यता से वही गुणनखंड अंश और हर दोनों में आ जाता है। चरण 3: यही साझा गुणनखंड सरलतम रूप से विरोध करता है।
