If \(a=\sqrt{75}\), then (a-8) is closest to which value on the number line?

Explanation opens after your attempt
Correct Answer

B. (0.66)

Step 1

Concept

\( \sqrt{75}\approx8.66 \), so \(a-8\approx0.66\). First estimate the root and then subtract.

Step 2

Why this answer is correct

The correct answer is B. (0.66). \( \sqrt{75}\approx8.66 \), so \(a-8\approx0.66\). First estimate the root and then subtract.

Step 3

Exam Tip

\( \sqrt{75}\approx8.66 \), इसलिए \(a-8\approx0.66\)। पहले मूल का अनुमान लगाएँ फिर घटाएँ।
