Question

Making use of the cube root table, find the cube root
133100

Answer 1

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:

$\sqrt[3]{100}=4.642$

$\therefore$ $\sqrt[3]{133100}=11\times \sqrt[3]{100}=11\times 4.642=51.062$
