On the number line, (\sqrt{9}) will be at the same position as which number?

Answer and explanation

Correct answer: (3)

The direct answer is option B: 3. The symbol \(\sqrt{9}\) means the principal, non-negative square root of 9. Since \(3\times3=9\), we have \(\sqrt9=3\), so the point is located at 3 on the number line. Option B is correct. Option A, 2, is wrong because \(2^2=4\), not 9. Option C, 9, is the number inside the root, not its square root; \(9^2=81\). Option D, -3, is also a square root of the equation \(x^2=9\), but it is not the value of the principal symbol \(\sqrt9\). This distinction matters: solving \(x^2=9\) gives \(x=\pm3\), whereas evaluating \(\sqrt9\) gives only 3. On the number line, mark the point three units to the right of zero. Memory cue: the radical sign gives the non-negative root unless a separate equation asks for all roots.
