Răspuns:

${ - 4}^{2} \times \frac{1}{4} - 0.5 \times \frac{4}{3} + \frac{2}{3} = \\ 16 \times \frac{1}{4} - \frac{5}{10} \times \frac{4}{3} + \frac{2}{3} = \\ \frac{16}{4} - \frac{20}{30} + \frac{2}{3} = \\ 4 - \frac{2}{3} + \frac{2}{3} = \\ \frac{12}{3} - \frac{2}{3} + \frac{2}{3} = \\ \frac{12}{3} = \\ = 4$
