f=3(2/9)^3-8(2/9)^2+5(2/9)-30

Lösung

f = 3 (\frac{2}{9})^{3} - 8 (\frac{2}{9})^{2} + 5 (\frac{2}{9}) - 30

f = - \frac{7108}{243}

Dezimale

f = - 29.25102 \dots

Schritte zur Lösung

f = 3 (\frac{2}{9})^{3} - 8 (\frac{2}{9})^{2} + 5 (\frac{2}{9}) - 30

Vereinfache

3 (\frac{2}{9})^{3} - 8 (\frac{2}{9})^{2} + 5 (\frac{2}{9}) - 30 : - \frac{7108}{243}

f = - \frac{7108}{243}

3 x - 4 = x + 6

- 8 = 4 (x - 1)

so l v e f or x, 2 y = 3 x + 6

10 - 2 x = 0

21 = 9 x + 3
