Question:
Find the value of \(?\) in: \(\sqrt{?} + 18 = \sqrt{3249}\)
समीकरण में \(?\) का मान ज्ञात कीजिए: \(\sqrt{?} + 18 = \sqrt{3249}\)
Options:
- 1764
- 1600
- 1681
- 1521
- 1764
- 1600
- 1681
- 1521
Correct Answer: d)
Explanation:
\(\sqrt{3249} = 57\).
\(\sqrt{?} + 18 = 57 \implies \sqrt{?} = 57 – 18 = 39\).
Squaring both sides:
\(? = 39^2 = 1521\).
\(\sqrt{3249} = 57\)।
\(\sqrt{?} = 57 – 18 = 39\)।
दोनों पक्षों का वर्ग करने पर: \(? = 39^2 = 1521\)।
