Question

is x^2+4x^3/2/√x a polynimal ?? justify your answer

Answer 1

We have,

${x}^{2} + \frac{4 {x}^{ \frac{3}{2} } }{ \sqrt{x} } \\ = {x}^{2} + 4 {x}^{ \frac{3}{2} } \times {x}^ { - \frac{1}{2} }$

Hence, it is clear that this is not a polynomial as the powers of x are not positive integers.

HOPE THIS COULD HELP!!!
