Simplify: (\sqrt{50}+\sqrt{8}-\sqrt{18}) is equal to which value?सरलीकृत कीजिए: (\sqrt{50}+\sqrt{8}-\sqrt{18}) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (,4\sqrt{2},)(,4\sqrt{2},)
Because (\sqrt{50}=5\sqrt{2}), (\sqrt{8}=2\sqrt{2}), and (\sqrt{18}=3\sqrt{2}), the answer is (4\sqrt{2}). In exams, combine only like surd terms.क्योंकि (\sqrt{50}=5\sqrt{2}), (\sqrt{8}=2\sqrt{2}) और (\sqrt{18}=3\sqrt{2}), इसलिए उत्तर (4\sqrt{2}) है। परीक्षा में समान surd terms को ही जोड़ें या घटाएं।
