What is the degree of \(8x^5+0x^7-2x^3+6\)?
B. (5)
\(0x^7\) शून्य पद है इसलिए उसे नहीं गिनते। सबसे बड़ी अशून्य घात (5) है। / \(0x^7\) is a zero term, so it is not counted. The highest non-zero power is (5).

After simplifying \(4x^3-4x^3+9x^2-5\), what will be the degree?
B. (2)
\(4x^3-4x^3=0\) होने से \(9x^2-5\) बचता है। इसकी डिग्री (2) है। / Since \(4x^3-4x^3=0\), \(9x^2-5\) remains. Its degree is (2).

If (p(x)=(a-3)x-6+2x-2-1) and (a=3), what is the degree of (p(x))?
C. (2)
(a=3) रखने पर \(x^6\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (2) है। / Putting (a=3) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (2).

For which value will the degree of ((k+5)x-4-7x+9) be (1)?
B. (k=-5)
डिग्री (1) के लिए \(x^4\) का गुणांक (0) होना चाहिए। (k+5=0) से (k=-5) मिलता है। / For degree (1), the coefficient of \(x^4\) must be (0). From (k+5=0), we get (k=-5).

The degree of \(-2x^8+5x^6-x^2+4\) is decided by which term?
A. \(-2x^8\)
सबसे बड़ी घात (8) वाले पद से डिग्री तय होती है। ऋणात्मक गुणांक डिग्री को नहीं बदलता। / The degree is decided by the term with highest power (8). A negative coefficient does not change the degree.

What is the degree of \(2x^2+x^9-6x^5+1\)?
D. (9)
पद घटते क्रम में नहीं हैं पर सबसे बड़ी घात (9) है। इसलिए डिग्री (9) है। / The terms are not in descending order, but the highest power is (9). Therefore the degree is (9).
