kalau salah tolong benerin ya

A.
13³ - 11³ - 2³
= 2.197 - 1.331 - 8
= 858

B.
[tex] \frac{ \sqrt[3]{64} + \sqrt[3]{729} - \sqrt[3]{1.331} }{ \sqrt[3]{125} \times \sqrt[3]{512} } \\ = \frac{4 + 9 - 11}{5 \times 8} \\ = \frac{13 - 11}{40} \\ = \frac{2}{40} \\ = \frac{2 \div 2}{40 \div 2} \\ = \frac{1}{20} [/tex]

Maaf Kalau Salah
