यदि \(x^4+ax^2+7\) की डिग्री (4) है, तो (a) के लिए सही कथन क्या है?
If the degree of \(x^4+ax^2+7\) is (4), what is the correct statement about (a)?
Explanation opens after your attempt
A. (a) कोई भी वास्तविक संख्या हो सकता है(a) can be any real number
Concept
The coefficient of \(x^4\) is (1), which is non-zero. So the value of (a) does not change degree (4).
Why this answer is correct
The correct answer is A. (a) कोई भी वास्तविक संख्या हो सकता है / (a) can be any real number. The coefficient of \(x^4\) is (1), which is non-zero. So the value of (a) does not change degree (4).
Exam Tip
\(x^4\) का गुणांक (1) है जो शून्य नहीं है। इसलिए (a) का मान डिग्री (4) को नहीं बदलता।
