Question

what is the cube root of 8?

Explanation:

Step1: Recall cube - root definition

The cube root of a number \(x\) is a number \(y\) such that \(y^3=x\). Let \(y = \sqrt[3]{8}\), we need to find \(y\) where \(y^3=8\).

Step2: Find the number

We know that \(2\times2\times2 = 2^3=8\). So \(\sqrt[3]{8}=2\).
