Answer 2

Răspuns:

$(1 - \frac{1}{2} ) {}^{2} + (3 - \frac{1}{3}) {}^{2} - 7 \frac{1}{9} = ( \frac{1}{2}) {}^{2} = \frac{2}{4} + \frac{4}{3} - 7 \frac{1}{9} = \frac{8}{18} + \frac{24}{18} - 7\frac{2}{18} = \frac{32}{18} - 7 \frac{2}{18} = \frac{32}{18} - \frac{128}{18} = \frac{94}{18} {}^{(2} = \frac{47}{9} = 5\frac{2}{9}$
