Question

Determine if the expression - 8n ^ 2 * m ^ 4 + 9m ^ - 1 * n ^ 2 + 6n ^ 4 * is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

Answer 1

Step-by-step explanation:

In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

since there is a term of m^-1 (a negative exponent) that we cannot combine with others (as it is not multiplied with another m-based term), it is NOT a polynomial.
