Answer

El producto es \(40a^4b^5c^7 + 128a^3b^4c^6 - 96a^2b^3c^7\).

Solution

1. Multiplicamos \(8a^2b^3c^4\) por cada uno de los términos dentro del paréntesis. 2. Primer término: \[ 8a^2b^3c^4 \cdot 5a^2b^2c^3 = (8 \cdot 5)(a^{2+2})(b^{3+2})(c^{4+3}) = 40a^4b^5c^7. \] 3. Segundo término: \[ 8a^2b^3c^4 \cdot 16ab c^2 = (8 \cdot 16)(a^{2+1})(b^{3+1})(c^{4+2}) = 128a^3b^4c^6. \] 4. Tercer término: \[ 8a^2b^3c^4 \cdot (-12c^3) = (8 \cdot -12)(a^2)(b^3)(c^{4+3}) = -96a^2b^3c^7. \] 5. Sumamos los resultados: \[ 40a^4b^5c^7 + 128a^3b^4c^6 - 96a^2b^3c^7. \]

Beyond the Answer

Para calcular el producto, primero aplicamos la propiedad distributiva. Multiplicamos cada término del primer paréntesis por cada término del segundo paréntesis: 1. \( 8 a^2 b^3 c^4 \cdot 5 a^2 b^2 c^3 = 40 a^{4} b^{5} c^{7} \) 2. \( 8 a^2 b^3 c^4 \cdot 16 a b c^{2} = 128 a^{3} b^{4} c^{6} \) 3. \( 8 a^2 b^3 c^4 \cdot (-12 c^{3}) = -96 a^{2} b^{3} c^{7} \) Ahora, sumamos todos estos productos: \[ 40 a^{4} b^{5} c^{7} + 128 a^{3} b^{4} c^{6} - 96 a^{2} b^{3} c^{7} \] Y, al juntar términos semejantes, la expresión final es: \[ 40 a^{4} b^{5} c^{7} + 128 a^{3} b^{4} c^{6} - 96 a^{2} b^{3} c^{7} \] Así hemos calculado el producto de la expresión.
