Explanation:

Step1: Substitute x = 6 into the function

Substitute \(x = 6\) into \(f(x)=\sqrt[3]{5x - 10}\), we get \(f(6)=\sqrt[3]{5\times6 - 10}\).

Step2: Calculate the value inside the cube - root

First, calculate \(5\times6-10\): \(5\times6 - 10=30 - 10=20\). So \(f(6)=\sqrt[3]{20}\).

Answer:

\(\sqrt[3]{20}\)
