प्रश्न
State whether the given algebraic expression is polynomial. Justify.
`2m^(-2) + 7m - 5`
उत्तर
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.
