किस (k) के लिए \(x^k+2x-5\) (x) में बहुपद होगा?
For which (k) will \(x^k+2x-5\) be a polynomial in (x)?
Explanation opens after your attempt
C. (k=4)
Concept
In a polynomial, the variable power must be a non-negative integer. Only (k=4) satisfies the condition.
Why this answer is correct
The correct answer is C. (k=4). In a polynomial, the variable power must be a non-negative integer. Only (k=4) satisfies the condition.
Exam Tip
बहुपद में चर की घात शून्य या धनात्मक पूर्णांक होनी चाहिए। (k=4) ही दी गई शर्त पूरी करता है।
