State Whether the Given Algebraic Expression Are Polynomial? Justify.

2m^(-2) + 7m - 5

#### Solution

In an algebraic expression, if the powers of the variables are whole numbers then the algebraic expression is a polynomial.

2m^(-2) + 7m - 5

Here, one of the powers of m is −2, which is not a whole number. So, 2m^(-2) + 7m - 5 is not a polynomial.
