निम्न में से कौन सा व्यंजक (x) में बहुपद है और उसकी डिग्री (4) है?
Which expression is a polynomial in (x) and has degree (4)?
Explanation opens after your attempt
B. \(3x^4-\sqrt{5}x^2+6\)
Concept
In the second expression, the powers are (4), (2), and (0), and the coefficients are real. So it is a polynomial of degree (4).
Why this answer is correct
The correct answer is B. \(3x^4-\sqrt{5}x^2+6\). In the second expression, the powers are (4), (2), and (0), and the coefficients are real. So it is a polynomial of degree (4).
Exam Tip
दूसरे व्यंजक में घातें (4), (2), और (0) हैं तथा गुणांक वास्तविक हैं। इसलिए यह डिग्री (4) का बहुपद है।
