For nonzero (k), (k,k^2,k^3) form an AP. What is the value of (k)?शून्येतर (k) के लिए (k,k^2,k^3) समांतर श्रेणी बनाते हैं। (k) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (k=1)(k=1)
The condition (2k^2=k+k^3) gives (k(k-1)^2=0), and the nonzero value is (1). In exams, do not ignore conditions like nonzero.शर्त (2k^2=k+k^3) से (k(k-1)^2=0) मिलता है, और शून्येतर मान (1) है। परीक्षा में शून्येतर जैसी शर्त न भूलें।
