Exercise 41 Page 395

Rearrange the radical equation so that one of the radical expressions is isolated. Then, raise both sides of the equation to a power equal to the index of the radicals.

Practice makes perfect

We will find and check the solutions of the given equation.

Finding the Solutions

To solve equations with a variable expression inside a radical, we will first rearrange the radical equation so that one of the radical expressions is isolated. Then, we can raise both sides of the equation to a power equal to the index of the radicals. Let's try to solve our equation using this method!
Since we still have a radical expression on one side of the equation, we will isolate the radical and then follow the same method.
