Answer

La expresión simplificada es \( a^6 b^{10} \).

Solution

Para simplificar la expresión \[ \left(\frac{a^{3} b^{3}}{b^{-2}}\right)^{2} \] seguimos los siguientes pasos: 1. Simplificamos el interior del paréntesis. En el denominador tenemos \( b^{-2} \), lo que equivale a multiplicar por \( b^{2} \): \[ \frac{a^{3} b^{3}}{b^{-2}} = a^3 b^{3} \cdot b^{2} = a^3 b^{3+2} = a^3 b^5. \] 2. Elevamos el resultado al cuadrado aplicando la propiedad \( (xy)^n = x^n y^n \): \[ \left(a^3 b^5\right)^2 = a^{3 \cdot 2} b^{5 \cdot 2} = a^6 b^{10}. \] La expresión simplificada con exponentes positivos es: \[ a^6 b^{10}. \]

Para simplificar la expresión \(\left(\frac{a^{3} b^{3}}{b^{-2}}\right)^{2}\), comenzamos por simplificar la fracción dentro del paréntesis. Recuerda que dividir entre una potencia de base \(b\) equivale a restar exponentes: \[ \frac{a^{3} b^{3}}{b^{-2}} = a^{3} b^{3 - (-2)} = a^{3} b^{3 + 2} = a^{3} b^{5}. \] Ahora, elevamos toda la expresión al cuadrado: \[ (a^{3} b^{5})^{2} = a^{3 \cdot 2} b^{5 \cdot 2} = a^{6} b^{10}. \] Así, la expresión simplificada es: \[ a^{6} b^{10}. \]
