Chapter A.3, Problem 14AYU

To determine

To find: Whether the expression is a monomial. If it is, name the variable and the coefficient, and give the degree of the monomial. If it is not a monomial, state why not.

Answer to Problem 14AYU

Not a monomial; the exponent of the variable is not a nonnegative integer.

Explanation of Solution

Given:

$-2x^{-3}$

Calculation:

A monomial in one variable is the product of a constant and a variable raised to a nonnegative integer power.

Given, $-2x^{-3}$. Therefore the expression is not a monomial, the exponent of the variable is not a nonnegative integer.
