If \(x=\frac{\sqrt{81}}{4}\), which value correctly represents \(x\) on the number line?

Answer and explanation

Correct answer: \(\frac{9}{4}\)

Since \(\sqrt{81}=9\), we get \(x=\frac{9}{4}\). Option B incorrectly uses 81 instead of its square root, while options C and D do not result from the given expression. In the exam, simplify the square root first and then perform the division.
