How many non-zero terms are there in (6x^4-2x^3+0x^2+5x-9)?बहुपद (6x^4-2x^3+0x^2+5x-9) में कुल कितने अशून्य पद हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 44
The terms are \(6x^4\), \(-2x^3\), \(0x^2\), \(5x\), and \(-9\). Since the coefficient of \(0x^2\) is 0, it is not a non-zero term. The other four terms are non-zero, so the answer is 4. Choosing 5 is a common mistake because it counts the zero term as well. Exam tip: Count only terms whose coefficients are not zero.बहुपद के पद हैं: \(6x^4\), \(-2x^3\), \(0x^2\), \(5x\) और \(-9\)। \(0x^2\) का गुणांक 0 है, इसलिए यह अशून्य पद नहीं है। शेष चार पद अशून्य हैं, अतः सही उत्तर 4 है। 5 चुनना एक सामान्य भूल है, क्योंकि उसमें शून्य पद को भी गिन लिया जाता है। परीक्षा टिप: केवल उन पदों को गिनें जिनका गुणांक शून्य न हो।
