Functions: Power functions and root functions
Solving root equations with substitution: Step 1/3
Most of the exercises in this package will use substitution in order to solve difficult equations involving roots. However, we can also use this technique on easier examples, as we will see in this exercise.
In order to get you more familiar with substitution for root equations, we will guide you step-by-step through the process of solving the following equation using substitution:
\[4\cdot x = 3\cdot \sqrt{x}\]We start by applying the substitution #u=\sqrt{x}#. What is the resulting equation if we carry out this substitution?
