Which conclusion is correct for x⁰ + √2x⁵ − 4x²/9?

Answer and explanation

Correct answer: It is a polynomial and its degree is 5

A polynomial in x may have real coefficients, including irrational numbers such as √2 and fractional numbers such as −4/9. The essential restriction is on the exponents of x: they must be non-negative integers. In the given expression, x⁰ is a constant term, √2x⁵ has exponent 5, and −4x²/9 has exponent 2. Every exponent is therefore allowed, and the coefficient of x⁵ is non-zero. The greatest exponent is 5, so the expression is a polynomial of degree 5. Option B is correct. Options A and D impose an incorrect restriction that coefficients must be integers, while C is wrong because the expression contains non-zero terms.
