If (r) is rational and (x) is irrational then what is (r+x) generally when (r=5) and (x=\sqrt{2})?यदि (r) परिमेय है और (x) अपरिमेय है तो (r+x) सामान्यतः क्या होगा जब (r=5) और (x=\sqrt{2})?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Irrationalअपरिमेय
(5+\sqrt{2}) is irrational because adding a rational and an irrational gives an irrational. In such questions watch the irrational part.(5+\sqrt{2}) अपरिमेय है क्योंकि परिमेय में अपरिमेय जोड़ने से अपरिमेय मिलता है। ऐसे सवाल में अपरिमेय भाग देखें।
