Making use of the cube root table, find the cube root
133100 .
Advertisements
Solution
We have: \[133100 = 1331 \times 100 \Rightarrow \sqrt[3]{133100} = \sqrt[3]{1331 \times 100} = 11 \times \sqrt[3]{100}\]
By cube root table, we have:
\[\sqrt[3]{100} = 4 . 642\]
∴ \[\sqrt[3]{133100} = 11 \times \sqrt[3]{100} = 11 \times 4 . 642 = 51 . 062\]
