Which expression is not a polynomial because it contains \(\frac{1}{x^3}\)?
B. \(4+\frac{1}{x^3}\)
\(\frac{1}{x^3}=x^{-3}\) होता है। ऋणात्मक घात के कारण यह बहुपद नहीं है। / \(\frac{1}{x^3}=x^{-3}\). Due to the negative power, it is not a polynomial.

What are the number of terms and degree in \(3x^2-7\)?
A. (2) पद और घात (2)(2) terms and degree (2)
\(3x^2-7\) में दो पद हैं और सबसे बड़ी घात (2) है। इसलिए यह द्विघात द्विपदी है। / \(3x^2-7\) has two terms and the highest power is (2). So it is a quadratic binomial.

Which expression is not a polynomial in (n)?
C. (n^{43}+2)
\(n^{4/3}\) की घात पूर्णांक नहीं है। बहुपद में चर की घातें शून्य या धनात्मक पूर्णांक होनी चाहिए। / The power in \(n^{4/3}\) is not an integer. In a polynomial, variable powers must be non-negative integers.

If (a=0) in (p(x)=2x-3+ax-2+5), which statement is correct?
B. घात (3) रहेगीThe degree remains (3)
(a=0) पर \(x^2\) वाला पद हटता है लेकिन \(2x^3\) रहता है। इसलिए घात (3) ही रहेगी। / When (a=0), the \(x^2\) term disappears but \(2x^3\) remains. Therefore, the degree stays (3).

Which option gives a correct example according to the definition of polynomial?
A. \(x^2+4x+4\) क्योंकि घातें (2), (1), (0) हैं\(x^2+4x+4\) because powers are (2), (1), (0)
\(x^2+4x+4\) में सभी घातें शून्य या धनात्मक पूर्णांक हैं। इसलिए यह सही बहुपद उदाहरण है। / In \(x^2+4x+4\), all powers are non-negative integers. So it is a correct polynomial example.

Which expression is a polynomial in (x) while (y) acts like a coefficient?
A. \(y^2x^3-4x+6\)
(x) के संदर्भ में \(y^2\) गुणांक की तरह माना जा सकता है। (x) की घातें (3), (1) और (0) हैं। / With respect to (x), \(y^2\) can be treated like a coefficient. The powers of (x) are (3), (1), and (0).

Which expression is a polynomial having only even powers?
A. \(x^6+2x^4-x^2+9\)
\(x^6+2x^4-x^2+9\) में घातें (6), (4), (2) और (0) हैं। ये सभी सम और मान्य हैं। / In \(x^6+2x^4-x^2+9\), the powers are (6), (4), (2), and (0). All are even and valid.

How many terms are there in \(x^4+2x^3+x^2+x+1\)?
C. (5)
इस बहुपद में (5) अलग-अलग पद हैं। जोड़ के चिन्हों से पदों को अलग पहचानें। / This polynomial has (5) distinct terms. Use plus signs to identify the terms separately.

What is the correct identification of \(x^2-3x+2\)?
A. द्विघात त्रिपदी बहुपदQuadratic trinomial polynomial
इसकी घात (2) है और इसमें (3) पद हैं। इसलिए यह द्विघात त्रिपदी बहुपद है। / Its degree is (2) and it has (3) terms. Therefore, it is a quadratic trinomial polynomial.

Which expression is not a polynomial in (x) because it has (x) in the denominator?
C. \(\frac{x^2+1}{x}\)
\(\frac{x^2+1}{x}=x+\frac{1}{x}\) में \(\frac{1}{x}\) की घात (-1) है। इसलिए यह बहुपद नहीं है। / \(\frac{x^2+1}{x}=x+\frac{1}{x}\) contains \(\frac{1}{x}\), whose power is (-1). Therefore, it is not a polynomial.
