Question

8. Determine o monômio expresso pela multiplicação (-a).(-m).(-m²).(-a) e dê o valor numérico desse monômio quando a =1/4 e m=-2​

Answer 1

$\sf\:( - a) \cdot( - m) \cdot\Big( - m {}^{2} \Big) \cdot( - a) \\ \\ \\ \sf\: - \Bigg( + \frac{1}{4} \Bigg) \cdot\Bigg( -\Big( - 2 {}^{2} \Big) \Bigg) \cdot - \Bigg( + \frac{1}{4} \Bigg) \\ \\ \\ \sf\: - \frac{1}{4} \cdot2 \cdot\Bigg( - \Big( - 2 {}^{2} \Big)\Bigg) \cdot\Bigg( - \frac{1}{4} \Bigg) \\ \\ \\ \sf\: - \frac{1}{4} \cdot2 \cdot2 {}^{2} \cdot\Bigg( - \frac{1}{4} \Bigg) \\ \\ \\ \sf\: \frac{1}{4} \cdot2 \cdot 2 {}^{2} \cdot \frac{1}{4} \\ \\ \\ \sf\:\frac{1}{2} \cdot2 {}^{2} \cdot \frac{1}{4} \\ \\ \\ \sf\:2 \cdot \frac{1}{4} \\ \\ \\ \sf\: \frac{1}{2}$
