Simplify (\(\sqrt{50}\) - \(\sqrt{8}\))
\(\20\sqrt{2}\)
\(\3\sqrt{2}\)
\(\10\sqrt{2}\)
\(\200\sqrt{2}\)
Answer: B
Solution: \(\sqrt{50}-\sqrt{8}=\sqrt{25\times2}-\sqrt{4\times2}=5\sqrt{2}-2\sqrt{2}=3\sqrt{2}\). Trick: Take out perfect-square factors from under each square root, then subtract like surds.
सरल कीजिए: \(\sqrt{50}-\sqrt{8}\)
\(\20\sqrt{2}\)
\(\3\sqrt{2}\)
\(\10\sqrt{2}\)
\(\200\sqrt{2}\)
उत्तर: B
हल: \(\sqrt{50}-\sqrt{8}=\sqrt{25\times2}-\sqrt{4\times2}=5\sqrt{2}-2\sqrt{2}=3\sqrt{2}\)। ट्रिक: दोनों वर्गमूलों के अंदर से पूर्ण वर्ग गुणनखंड बाहर निकालें और फिर सजातीय करणी पदों को घटाएँ।
