Which algebraic expression is a polynomial?

A polynomial is an expression with variables and coefficients separated by addition and subtraction. The following are used when determining if an expression is a polynomial:

i) Variables of a polynomial must not have negative exponent.

ii) Variables of a polynomial must not have fractional exponent.

iii) Dividing by an exponent is not allowed

iv) Exponent radicals are not allowed.

a) is not a polynomial because dividing by an exponent is not allowed.

b) , is not a polynomial because exponent radicals are not allowed (√m)

c) is not a polynomial because dividing by an exponent is not allowed.

d) is a polynomial
