# Tell whether 5x^(1/2) – 3x^3 is a polynomial.

Polynomials
Tell whether $$5x^{1/2} - 3x^{3}$$ is a polynomial.
Polynomial is a mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a non-negative integral power. In $$5x^{1/2} - 3x^{3}$$, x has power 1/2 (not integral), so that’s not a polynomial.
