Correct Answer

C. (5)

Step 1

Concept

((5x)2=x\cdot125), so \(25x^2=125x\) and positive (x=5). Do not take zero as a positive solution.

Step 2

Why this answer is correct

The correct answer is C. (5). ((5x)2=x\cdot125), so \(25x^2=125x\) and positive (x=5). Do not take zero as a positive solution.

Step 3

Exam Tip

((5x)2=x\cdot125), इसलिए \(25x^2=125x\) और धनात्मक (x=5)। शून्य को धनात्मक हल में नहीं लें।
