2. Answer:

   1) 4x^3/2+/x^1/2 is not a polynomial

   Step-by-step explanation:

   (a) x

   2

   ×

   x

   1

   =x

   2

   +x

   −1

   is not a polynomial since the exponent of variable in 2nd term is negative.

   (b) 2x

   2

   −3

   x

   +1=2x

   2

   −3x

   2

   1

   +1 is not a polynomial, since the exponent of variable in 2nd terms is a rational number.

   (c) x

   3

   −3x+1 is a polynomial.

   (d) 2x

   2

   3

   −5x is also not a polynomial, since the exponents of variable in 1st term is a rational number.

   hope it’s helpful to you!
