गुणोत्तर श्रेढ़ी के लगातार तीन पद (x,3x,27) हैं। धनात्मक (x) क्या है?
The consecutive terms of a geometric progression are (x,3x,27). What is the positive (x)?
Explanation opens after your attempt
C. (3)
Concept
((3x)2=x\cdot27), so \(9x^2=27x\) and positive (x=3). Do not take zero as a positive solution.
Why this answer is correct
The correct answer is C. (3). ((3x)2=x\cdot27), so \(9x^2=27x\) and positive (x=3). Do not take zero as a positive solution.
Exam Tip
((3x)2=x\cdot27), इसलिए \(9x^2=27x\) और धनात्मक (x=3)। शून्य को धनात्मक हल में नहीं लें।
