Question

Is X - ^6 a polynomial?

Answer 1

Answer:

$X^{-6}$ is not a polynomial.

Step-by-step explanation:

Given : an expression $X^{-6}$

We have to check whether given expression $X^{-6}$ is a polynomial or not.

An expression is said to be polynomial if it is the collection of constant and one or several variables having non negative integer power or degree.

Example : $2x^2+3x+1, x^5,m^2+n^5$

For the given expression $X^{-6}$ the variable term is X is having power of -6 which is negative.

Hence, $X^{-6}$ is not a polynomial.
