[AI-generated answer — Bot GPT 3.5]

To solve the equation √x-1=2, we need to isolate the square root term on one side of the equation.

√x - 1 = 2
√x = 2 + 1
√x = 3

Now, to get rid of the square root, we need to square both sides of the equation.

(√x)^2 = 3^2
x = 9

Therefore, the solution to the equation √x - 1 = 2 is x = 9.
