•SE POSSÍVEL SIMPLIFIQUE.

Answer 1

Explicação passo-a-passo:

$m) \frac{1}{2} .( \frac{2}{3} - \frac{1}{6} ) = \frac{1}{2} .( \frac{4 - 1}{6} ) = \frac{1}{2} . \frac{3}{2} = \frac{3}{4}$

$n) \frac{3}{4} .( \frac{1}{4} - \frac{1}{6} ) = \frac{3}{4} .( \frac{3 - 2}{12} ) = \frac{3}{4} . \frac{1}{12} = \frac{3}{48 } = \frac{1}{16}$

$p)( - \frac{4}{5} ) {}^{2} = - \frac{4}{5} \times - \frac{4}{5} = \frac{16}{25}$

$q)( \frac{1}{2} - \frac{1}{3} ) {}^{2} . \frac{3}{5} = ( \frac{3 - 2}{6} ) {}^{2} . \frac{3}{5} = ( \frac{1}{6} ) {}^{2} . \frac{3}{5} = \frac{1}{36} . \frac{3}{5} = \frac{3}{180} = \frac{1}{60}$
