To solve the given expression, we need to evaluate the numerator and the denominator separately and then divide the results. The numerator is \(3 \times 2^2 \times 1^3\) and the denominator is \(3^2 \times 2 \times 1^{-1}\). Simplify each part and then perform the division.
Paso 1: Evaluación del Numerador
Calculamos el numerador de la expresión:
\[
3 \times 2^2 \times 1^3 = 3 \times 4 \times 1 = 12
\]
