Question

Making use of the cube root table, find the cube root
7000

Answer 1

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: 

\[\sqrt[3]{7} = 1 . 913 \text{ and } \sqrt[3]{1000} = 10\]

∴ \[\sqrt[3]{7000} = \sqrt[3]{7} \times \sqrt[3]{1000} = 1 . 913 \times 10 = 19 . 13\]
