Odpowiedź:
[tex]\sqrt[3]{\frac{1}{27} } * \sqrt[3]{8} - \frac{\sqrt{169} }{\sqrt{100} } = \frac{1}{3} * 2 - \frac{13}{10} = \frac{2}{3} - \frac{13}{10} = \frac{20}{30} - \frac{39}{30} = -\frac{19}{30}[/tex]
Szczegółowe wyjaśnienie:
∛1/27 * ∛8 - √169/√100 = 1/3 * 2 - 13/10 = 2/3 - 1 3/10 = 20/30 - 1 9/30 =
= 20/30 - 39/30 = -19/30
