7x^4 (Simplify your answer ) Classify the polynomial. The polynomial is a square square square quadratic cubic quartic

To simplify the expression $7x^{4}$, we can simply write it as $7x^{4}$ since there are no like terms to combine.<br /><br />Now, let's classify the polynomial based on the degree of the highest power of the variable.<br /><br />The degree of a polynomial is determined by the highest power of the variable in the polynomial. In this case, the highest power of the variable $x$ is 4.<br /><br />Therefore, the polynomial $7x^{4}$ is a quartic polynomial.<br /><br />So, the classification of the polynomial is:<br /><br />The polynomial is a quartic polynomial.
