Which polynomial has degree \(4\)?किस बहुपद की कोटि (degree) \(4\) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(-5x^4+2x^2+1\)\(-5x^4+2x^2+1\)
A polynomial has degree \(4\) if the highest power of \(x\) appearing in it is \(4\). In \(-5x^4+2x^2+1\), the highest power is \(x^4\) with nonzero coefficient \(-5\). So its degree is \(4\).किसी बहुपद की कोटि \(4\) होती है यदि उसमें \(x\) का सबसे बड़ा घातांक \(4\) हो। \(-5x^4+2x^2+1\) में सबसे बड़ा घात \(x^4\) है और इसका गुणांक \(-5\) (शून्य नहीं) है। इसलिए इसकी कोटि \(4\) है।
