Question 1/2
Easy Mathematics
Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 18
यदि \(\sqrt{3}=\frac{p}{q}\), तो वर्ग करने पर दाईं ओर क्या बनेगा?
If \(\sqrt{3}=\frac{p}{q}\), what does the right side become after squaring?
#fraction square
#sqrt3 proof
#class 10
A \(p^2q^2\)
B \(\frac{p}{q^2}\)
C \(\frac{p^2}{q^2}\)
D \(\frac{3p}{q}\)
Explanation opens after your attempt
Correct Answer
C. \(\frac{p^2}{q^2}\)
Step 1
Concept
While squaring a fraction, both numerator and denominator are squared.
Step 2
Why this answer is correct
Hence (\left\(\frac{p}{q}\right\)2 =\frac{p-2 }{q-2 }).
Step 3
Exam Tip
Squaring only the numerator is a common mistake. चरण 1: भिन्न का वर्ग करते समय अंश और हर दोनों का वर्ग होता है। चरण 2: इसलिए (\left\(\frac{p}{q}\right\)2 =\frac{p-2 }{q-2 })। चरण 3: केवल अंश का वर्ग करना सामान्य गलती है।

Question 2/2
Easy Mathematics
Chapter 1: Real Numbers 6: Proof of irrationality of √2, √3, √5 Class 10 Level 17
यदि \(\sqrt{3}=\frac{a}{b}\), तो वर्ग करने पर दाईं ओर क्या बनेगा?
If \(\sqrt{3}=\frac{a}{b}\), what will the right side become after squaring?
#fraction square
#sqrt3 proof
#class 10
A \(\frac{a^2}{b^2}\)
B \(\frac{a}{b^2}\)
C \(\frac{a^2}{b}\)
D \(\frac{3a}{b}\)
Explanation opens after your attempt
Correct Answer
A. \(\frac{a^2}{b^2}\)
Step 1
Concept
While squaring a fraction, both numerator and denominator are squared.
Step 2
Why this answer is correct
Therefore (\left\(\frac{a}{b}\right\)2 =\frac{a-2 }{b-2 }).
Step 3
Exam Tip
Squaring only the numerator is a mistake. चरण 1: भिन्न का वर्ग करते समय अंश और हर दोनों का वर्ग होता है। चरण 2: इसलिए (\left\(\frac{a}{b}\right\)2 =\frac{a-2 }{b-2 })। चरण 3: भिन्न के वर्ग में केवल अंश का वर्ग करना गलती है।
