Vedclass · Answer

(C) polynomial is an algebraic expression where the exponents of the variable must be non-negative integers.In option $A$,$4x^2 + \sqrt{7}$,the exponent of $x$ is $2$,which is a non-negative integer.In option $B$,$3x^2 + x - 1$,the exponents of $x$ are $2$ and $1$,which are non-negative integers.In option $C$,$3x^2 - 5\sqrt{x} + 2$,the term $\sqrt{x}$ can be written as $x^{1/2}$. Since $1/2$ is not an integer,this expression is not a polynomial.In option $D$,$3x - 1$,the exponent of $x$ is $1$,which is a non-negative integer.Therefore,$3x^2 - 5\sqrt{x} + 2$ is not a polynomial.

Which of the following is not a polynomial in variable $x$?
