2. Tub ko‘paytuvchilarga ajratishdan foydalanib quyidagi sonlarning kub ildizini toping: a) ∛343; b) ∛512; d) ∛729; e) ∛1331; f) ∛4096; g) ∛8000.

Sonlarni kub darajalar ko‘rinishida yozamiz:

1. \(\sqrt[3]{343}=\sqrt[3]{7^3}=7\);
2. \(\sqrt[3]{512}=\sqrt[3]{8^3}=8\);
3. \(\sqrt[3]{729}=\sqrt[3]{9^3}=9\);
4. \(\sqrt[3]{1331}=\sqrt[3]{11^3}=11\);
5. \(\sqrt[3]{4096}=\sqrt[3]{16^3}=16\);
6. \(\sqrt[3]{8000}=\sqrt[3]{20^3}=20\).

Javob: a) 7; b) 8; d) 9; e) 11; f) 16; g) 20.
