Vedclass · Answer

(B) The given expression is $1-\sqrt{5x} = 1-\sqrt{5} \cdot x^{\frac{1}{2}}$.$A$ polynomial is an algebraic expression in which the exponents of all variables must be non-negative integers (whole numbers).In the term $\sqrt{5} \cdot x^{\frac{1}{2}}$,the exponent of the variable $x$ is $\frac{1}{2}$,which is not a whole number.Therefore,the given expression is not a polynomial.
