किस विकल्प में (\left\(ab^{-2}\right\)^{3}\cdot a^{-1}b^{5}) का सही सरल रूप है?
Which option gives the correct simplified form of (\left\(ab^{-2}\right\)^{3}\cdot a^{-1}b^{5})?
Explanation opens after your attempt
Correct Answer
A. \(a^{2}b^{-1}\)
Concept
We have (\left\(ab^{-2}\right\)^{3}=a^{3}b^{-6}), and multiplying by \(a^{-1}b^{5}\) gives \(a^{2}b^{-1}\). In exams, add exponents separately for each variable.
Why this answer is correct
The correct answer is A. \(a^{2}b^{-1}\). We have (\left\(ab^{-2}\right\)^{3}=a^{3}b^{-6}), and multiplying by \(a^{-1}b^{5}\) gives \(a^{2}b^{-1}\). In exams, add exponents separately for each variable.
Exam Tip
(\left\(ab^{-2}\right\)^{3}=a^{3}b^{-6}), फिर \(a^{-1}b^{5}\) से गुणा करने पर \(a^{2}b^{-1}\) मिलता है। परीक्षा में हर चर की घात अलग-अलग जोड़ें।
