व्यंजक \(x^2+x^{-2}+x^0\) बहुपद है या नहीं?

Is \(x^2+x^{-2}+x^0\) a polynomial or not?

Explanation opens after your attempt
Correct Answer

C. नहीं, क्योंकि \(x^{-2}\) की घात ऋणात्मक हैNo, because \(x^{-2}\) has a negative power

Step 1

Concept

In \(x^{-2}\), the variable has a negative power. One invalid power makes the expression not a polynomial.

Step 2

Why this answer is correct

The correct answer is C. नहीं, क्योंकि \(x^{-2}\) की घात ऋणात्मक है / No, because \(x^{-2}\) has a negative power. In \(x^{-2}\), the variable has a negative power. One invalid power makes the expression not a polynomial.

Step 3

Exam Tip

\(x^{-2}\) में चर की घात ऋणात्मक है। एक अमान्य घात के कारण व्यंजक बहुपद नहीं होता।

Open Question Page
Ask Friends

क्या \(2x^0-3x\) बहुपद है?

Is \(2x^0-3x\) a polynomial?

Explanation opens after your attempt
Correct Answer

A. हां, क्योंकि \(x^0=1\) और (x) की घात (1) हैYes, because \(x^0=1\) and the power of (x) is (1)

Step 1

Concept

The power in \(x^0\) is (0), which is valid in a polynomial. Therefore it is a polynomial.

Step 2

Why this answer is correct

The correct answer is A. हां, क्योंकि \(x^0=1\) और (x) की घात (1) है / Yes, because \(x^0=1\) and the power of (x) is (1). The power in \(x^0\) is (0), which is valid in a polynomial. Therefore it is a polynomial.

Step 3

Exam Tip

\(x^0\) की घात (0) है जो बहुपद में मान्य है। इसलिए यह बहुपद है।

कौन-सा कथन \(x^0+x^{-2}+3\) के लिए सही है?

Which statement is correct for \(x^0+x^{-2}+3\)?

Explanation opens after your attempt
Correct Answer

B. यह बहुपद नहीं है क्योंकि \(x^{-2}\) हैIt is not a polynomial because it has \(x^{-2}\)

Step 1

Concept

\(x^0\) is valid, but \(x^{-2}\) is invalid. Negative powers are not allowed in a polynomial.

Step 2

Why this answer is correct

The correct answer is B. यह बहुपद नहीं है क्योंकि \(x^{-2}\) है / It is not a polynomial because it has \(x^{-2}\). \(x^0\) is valid, but \(x^{-2}\) is invalid. Negative powers are not allowed in a polynomial.

Step 3

Exam Tip

\(x^0\) मान्य है, लेकिन \(x^{-2}\) अमान्य है। बहुपद में ऋणात्मक घात स्वीकार्य नहीं होती।

कौन-सा कथन \(x^0+x^{-1}+2\) के बारे में सही है?

Which statement is correct about \(x^0+x^{-1}+2\)?

Explanation opens after your attempt
Correct Answer

C. यह बहुपद नहीं है क्योंकि \(x^{-1}\) हैIt is not a polynomial because it has \(x^{-1}\)

Step 1

Concept

\(x^0\) is valid but \(x^{-1}\) is not valid. One invalid term prevents the whole expression from being a polynomial.

Step 2

Why this answer is correct

The correct answer is C. यह बहुपद नहीं है क्योंकि \(x^{-1}\) है / It is not a polynomial because it has \(x^{-1}\). \(x^0\) is valid but \(x^{-1}\) is not valid. One invalid term prevents the whole expression from being a polynomial.

Step 3

Exam Tip

\(x^0\) मान्य है लेकिन \(x^{-1}\) मान्य नहीं है। एक अमान्य पद पूरे व्यंजक को बहुपद नहीं रहने देता।
