Question

State whether the given algebraic expression is polynomial. Justify.

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

Answer 1

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.
