Question
Making use of the cube root table, find the cube root 7000
✓
Answer
We have:
700 = 70 × 100
$\therefore\sqrt[3]{7000}$
$=\sqrt[3]{7\times1000}$
$=\sqrt[3]{7}\times\sqrt[3]{1000}$
By the cube root table, we have:
$=\sqrt[3]{7}=1.913$ and $\sqrt[3]{1000}=10$
$\therefore\sqrt[3]{7000}$
$=\sqrt[3]{7}\times\sqrt[3]{1000}$
$=1.913\times10$
$=19.13$
700 = 70 × 100
$\therefore\sqrt[3]{7000}$
$=\sqrt[3]{7\times1000}$
$=\sqrt[3]{7}\times\sqrt[3]{1000}$
By the cube root table, we have:
$=\sqrt[3]{7}=1.913$ and $\sqrt[3]{1000}=10$
$\therefore\sqrt[3]{7000}$
$=\sqrt[3]{7}\times\sqrt[3]{1000}$
$=1.913\times10$
$=19.13$
