गुणोत्तर श्रेढ़ी के लगातार तीन पद (x,5x,125) हैं। धनात्मक (x) क्या है?
The consecutive terms of a geometric progression are (x,5x,125). What is the positive (x)?
Explanation opens after your attempt
C. (5)
Concept
((5x)2=x\cdot125), so \(25x^2=125x\) and positive (x=5). Do not take zero as a positive solution.
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.
Exam Tip
((5x)2=x\cdot125), इसलिए \(25x^2=125x\) और धनात्मक (x=5)। शून्य को धनात्मक हल में नहीं लें।
