Correct Answer

A. (20)

Step 1

Concept

\(x^2=4\cdot100=400\), so positive (x=20). The middle term is the geometric mean.

Step 2

Why this answer is correct

The correct answer is A. (20). \(x^2=4\cdot100=400\), so positive (x=20). The middle term is the geometric mean.

Step 3

Exam Tip

\(x^2=4\cdot100=400\), इसलिए धनात्मक (x=20)। मध्य पद ज्यामितीय माध्य होता है।
