Answer
The solution is \( x = \frac{9}{2} \).
Solution
To solve the equation √(4x - 17) = 1, follow these steps:
1. Since the square root function is defined only for nonnegative values, first set the expression inside the square root to be at least zero:
4x - 17 ≥ 0 ⟹ x ≥ 17/4.
2. Now, square both sides of the equation to eliminate the square root:
(√(4x - 17))² = 1² ⟹ 4x - 17 = 1.
3. Solve for x:
4x = 1 + 17 ⟹ 4x = 18,
x = 18/4 ⟹ x = 9/2.
4. Verify that the solution satisfies the original equation and the constraint x ≥ 17/4:
x = 9/2 (= 4.5) satisfies the inequality, and √(4*(9/2) - 17) = √(18 - 17) = √1 = 1, which is correct.
Therefore, the correct choice is:
A. The solution(s) is/are 9/2.

Extra Insights
To solve the equation \( \sqrt{4 x-17}=1 \), we start by squaring both sides to eliminate the square root: \[ 4x - 17 = 1^2 \] \[ 4x - 17 = 1 \] Next, we solve for \(x\): \[ 4x = 1 + 17 \] \[ 4x = 18 \] \[ x = \frac{18}{4} \] \[ x = \frac{9}{2} \] So the correct choice is: A. The solution(s) is/are \( \frac{9}{2} \).
