Final answer:
To solve the equation, add 11 to both sides and then square both sides
Step-by-step explanation:
To solve the equation √x - 11 = 5, we need to isolate the variable x. Firstly, we can add 11 to both sides of the equation to get √x = 16. To eliminate the square root, we square both sides of the equation, resulting in (√x)^2 = 16^2. This simplifies to x = 256.
