(\left\(\frac{4x^{3}y^{-2}}{2x^{-1}y^{4}}\right\)^{2}\cdot\frac{y^{12}}{x^{4}}) का सरल रूप क्या है?
Explanation opens after your attempt
Correct Answer
A. \(4x^{4}\)
Concept
Inside, \(\frac{4x^{3}y^{-2}}{2x^{-1}y^{4}}=2x^{4}y^{-6}\), and its square is \(4x^{8}y^{-12}\). Multiplying by \(\frac{y^{12}}{x^{4}}\) gives \(4x^{4}\).
Why this answer is correct
The correct answer is A. \(4x^{4}\). Inside, \(\frac{4x^{3}y^{-2}}{2x^{-1}y^{4}}=2x^{4}y^{-6}\), and its square is \(4x^{8}y^{-12}\). Multiplying by \(\frac{y^{12}}{x^{4}}\) gives \(4x^{4}\).
Exam Tip
अंदर \(\frac{4x^{3}y^{-2}}{2x^{-1}y^{4}}=2x^{4}y^{-6}\), इसका वर्ग \(4x^{8}y^{-12}\) है। फिर \(\frac{y^{12}}{x^{4}}\) से गुणा करने पर \(4x^{4}\) मिलता है।
