Easy Mathematics Chapter 1: Real Numbers Class 10 Level 16

यदि \(\sqrt{5}=\frac{p}{q}\), तो वर्ग करने पर क्या प्राप्त होगा?

If \(\sqrt{5}=\frac{p}{q}\), what is obtained after squaring?

Explanation opens after your attempt
Correct Answer

A. \(p^2=5q^2\)

Step 1

Concept

Squaring both sides gives \(5=\frac{p^2}{q^2}\).

Step 2

Why this answer is correct

Multiplying by \(q^2\) gives \(p^2=5q^2\).

Step 3

Exam Tip

Write the denominator-clearing step clearly. चरण 1: दोनों ओर वर्ग करें तो \(5=\frac{p^2}{q^2}\) मिलता है। चरण 2: \(q^2\) से गुणा करने पर \(p^2=5q^2\) मिलता है। चरण 3: हर को हटाने का चरण साफ लिखें।
