उत्तर
We have: \[7000 = 70 \times 100\]
∴ \[\sqrt[3]{7000} = \sqrt[3]{7 \times 1000} = \sqrt[3]{7} \times \sqrt[3]{1000}\]
By the cube root table, we have:
\[\sqrt[3]{7} = 1 . 913 \text{ and } \sqrt[3]{1000} = 10\]
∴ \[\sqrt[3]{7000} = \sqrt[3]{7} \times \sqrt[3]{1000} = 1 . 913 \times 10 = 19 . 13\]
