$$ 1- (\frac{k-1}{k})^4 > 0.45 $$
$$ - (\frac{k-1}{k})^4 > -0.55 $$
$$ (\frac{k-1}{k})^4 < 0.55 $$
$$ (\frac{k-1}{k}) < 0.55^{\frac{1}{4}} $$
$$ 1-\frac{1}{k} < 0.55^{\frac{1}{4}} $$
$$ 1-\frac{1}{k} < 0.55^{\frac{1}{4}} $$
$$ -\frac{1}{k} < 0.55^{\frac{1}{4}}-1 $$
$$ -k > \frac{1}{0.55^{\frac{1}{4}}-1} $$
$$ k < -\frac{1}{0.55^{\frac{1}{4}}-1} $$
Das wären so ungefähr: \( k < 7.2\)
