Passo 1: Multiplicar os coeficientes e somar os expoentes da mesma parte literal
Ex: 9m²
9 = coeficiente numérico
m² = parte lateral
[tex] - 3a {}^{2} b \times 5a \\ - 15 {a}^{2} ba \\ - 15 {a}^{2} b {a}^{1} \\ - 15 {a}^{2 + 1} b \\ \color{green}- 15 {a}^{3} b[/tex]
[tex] \frac{4x}{5} \times \frac{x}{2} = \frac{4x \div 2}{5} \times \frac{x}{2 \div 2} = \frac{2x}{5} \times x = \frac{2x \times x}{5} = \color{green} \frac{2 {x}^{2} }{5} [/tex]
[tex]3.8 {a}^{2} b \times ( - 2.5b) \\ - 3.8 {a}^{2} b \times 2.5b \\ - 9.5 {a}^{2} b \times b \\ \color{green} - 9.5 {a}^{2} {b}^{2} [/tex]
[tex]\displaystyle\int_ \empty ^ \mathbb{C} \frac{ - b \: ± \: \sqrt{ {b}^{2} - 4 \times a \times c } }{2 \times a} d{ t } \boxed{ \boxed{ \mathbb{\displaystyle\Re}\sf{ \gamma \alpha }\tt{ \pi}\bf{ \nabla}}}[/tex]
