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

Answer

We have:
133100 = 1331 × 100
$\Rightarrow\sqrt[3]{1331100}$
$=\sqrt[3]{1331\times100} $
$=11\times\sqrt[3]{100}$
By cube root table, we have:
$\sqrt[3]{100}=4.642 $
$\therefore\sqrt[3]{133100}$
$=11\times\sqrt[3]{100}$
$=11\times4.642$
$=51.062$
