Question
Making use of the cube root table, find the cube root
0.27
Solution
The number 0.27 can be written as \[\frac{27}{100}\] .
Now
\[\sqrt[3]{0 . 27} = \sqrt[3]{\frac{27}{100}} = \frac{\sqrt[3]{27}}{\sqrt[3]{100}} = \frac{3}{\sqrt[3]{100}}\]
By cube root table, we have:
\[\sqrt[3]{100} = 4 . 642\]
∴ \[\sqrt[3]{0 . 27} = \frac{3}{\sqrt[3]{100}} = \frac{3}{4 . 642} = 0 . 646\]
Thus, the required cube root is 0.646.
