Expert Mathematics Chapter 1: Real Numbers Class 10 Level 18

\(\sqrt{5}\) के प्रमाण में \(a^2=5b^2\) से \(5\mid a\) सिद्ध होने के बाद (a=5t) लिखा गया। यह किस बात का संकेत है?

In the proof for \(\sqrt{5}\), after \(5\mid a\) is proved from \(a^2=5b^2\), (a=5t) is written. What does this indicate?

Correct Answer

B. (a) (5) का गुणज है(a) is a multiple of (5)

Step 1

Concept

\(5\mid a\) means (a) is divisible by (5).

Step 2

Why this answer is correct

Divisibility is written in multiple form, so (a=5t).

Step 3

Exam Tip

This form helps prove divisibility of (b) next. चरण 1: \(5\mid a\) का अर्थ है कि (a) (5) से विभाज्य है। चरण 2: विभाज्यता को गुणज के रूप में लिखते हैं, इसलिए (a=5t)। चरण 3: यह रूप आगे (b) की विभाज्यता सिद्ध करने में मदद करता है।
