Answer 1

Resposta:

$l)4.(-\frac{1}{2} )^2 - (-\frac{1}{3} )$ ➛ $4.\frac{1}{4} - (-\frac{1}{3} )$ ➛ $4.\frac{1}{4} +\frac{1}{3}$ ➛ $\frac{4}{4} +\frac{1}{3}$ ➛ $1 +\frac{1}{3}$ ➛ $\frac{2}{3}$

$m)(1-\frac{1}{2} )^2 + (-1 + \frac{1}{2} )^3$ ➛ $(1-\frac{1}{4} ) + (-1 + \frac{1}{2} )^3$ ➛ $(1-\frac{1}{4} ) + (-1 + \frac{1}{8} )$ ➛ $(\frac{0}{4} ) + (-1 + \frac{1}{8} )$ ➛ $(\frac{0}{4} ) + ( \frac{0}{8} )$ ➛ $0 + 0$ ➛ $0$
