Simplifying (2xy2x3y2)2(12xy3x3y1)1\left(\frac{2xy^2}{x^3y^{-2}}\right)^2\left(\frac{12xy^3}{x^3y^{-1}}\right)^{-1} Using Exponent Properties

To simplify the expression (2xy2x3y2)2(12xy3x3y1)1\left(\frac{2xy^2}{x^3y^{-2}}\right)^2\left(\frac{12xy^3}{x^3y^{-1}}\right)^{-1}, apply multiple exponent properties. First, simplify inside the parentheses: (2y4x2)2(12y4x2)1\left(\frac{2y^4}{x^2}\right)^2\left(\frac{12y^4}{x^2}\right)^{-1}. Next, use the Quotient to a Power Property (ab)m=ambm\left(\frac{a}{b}\right)^m = \frac{a^m}{b^m} to distribute the outer exponents: (2y4)2(x2)2(12y4)1(x2)1\frac{(2y^4)^2}{(x^2)^2} \cdot \frac{(12y^4)^{-1}}{(x^2)^{-1}}. Then, apply the Product to a Power Property (ab)m=ambm(ab)^m = a^m b^m to distribute the exponents to the factors in the numerators: 4y8x4121y4x2\frac{4y^8}{x^4} \cdot \frac{12^{-1}y^{-4}}{x^{-2}}. Finally, simplify by combining terms to get 4y412x2\frac{4y^4}{12x^2}, which reduces to y43x2\frac{y^4}{3x^2}.
