A= 4/(sqrt(5)+1)+1

Lösung

A = \frac{4}{5 + 1} + 1

A = 5 - 1 + 1

Dezimale

A = 2.23606 \dots

Schritte zur Lösung

A = \frac{4}{5 + 1} + 1

\frac{4}{5 + 1} = 5 - 1

A = 5 - 1 + 1

\frac{1}{2} x - \frac{1}{3} + x - 5 = \frac{1}{4}

\frac{x}{0.7} - \frac{0.17 - 0.2 x}{0.03} = 1

6 x - 12 = 42

so l v e f or a, s = \frac{a - r l}{1 - r}

4 x + 2 = 16
