Question

Is x2+4x3/2/under root x a polynomial? Justify your answer.

Answer 1

Answer:

4 x ^(3/2) = 4 x √x

4 x ^(3/2) / √ x = 4x

So, x² + 4 x ^(3/2) / √ x = x² + 4x

x² + 4x is a polynomial

SO, its a polynomial

Step-by-step explanation:

Answer 2

Answer:

Yes, it is a polynomial. Now x^(1/2) will cancel out from both numerator and denominator. So x^4 + 4x^3 will left . And this is a polynomial.
