Which expression is a polynomial of degree (5)?

Answer and explanation

Correct answer: \(2x^5-x^2+3\)

In \(2x^5-x^2+3\), the powers of \(x\) are \(5\), \(2\), and \(0\). All are non-negative integers, so it is a polynomial. Its highest power is \(5\), hence its degree is \(5\). \(x^{5/2}+2\) has a fractional exponent, whereas \(x^{-5}+4\) and \(\frac{1}{x^5}+1\) have negative powers of \(x\); therefore, they are not polynomials. Exam tip: In a polynomial, an exponent of a variable can only be \(0,1,2,\ldots\).
