Schritte zur Lösung

\frac{40 - 20 ( 5 )}{5 ^{2}} + \frac{1}{2}

Apply rule:

(a) = a

(5) = 5

= \frac{40 - 20 \cdot 5}{5 ^{2}} + \frac{1}{2}

\frac{40 - 20 \cdot 5}{5 ^{2}} = - \frac{60}{25}

= - \frac{60}{25} + \frac{1}{2}

- \frac{60}{25} + \frac{1}{2} = - \frac{19}{10}

= - \frac{19}{10}

- 6 x - 6 x = 12

y^{2} = 2
