If (a>0) and (b>0), what is the simplified form of (\sqrt{a^2b^4})?यदि (a>0) और (b>0), तो (\sqrt{a^2b^4}) का सरल रूप क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (,ab^2,)(,ab^2,)
Because (\sqrt{a^2}=a) and (\sqrt{b^4}=b^2), the answer is (ab^2). In exams, note the condition that variables are positive.क्योंकि (\sqrt{a^2}=a) और (\sqrt{b^4}=b^2), इसलिए उत्तर (ab^2) है। परीक्षा में variables के positive होने की शर्त ध्यान रखें।
