    The degree of the polynomial \[\frac{{{\mathbf{x}}^{\mathbf{4}}}\mathbf{+}{{\mathbf{x}}^{\mathbf{5}}}\mathbf{-}{{\mathbf{x}}^{\mathbf{8}}}}{{{\mathbf{x}}^{\mathbf{3}}}}\] is

    A)  2                    

    B)  3             

    C)  4                                

    D)  5

    Correct Answer: D

    Solution :

    (d): \[\frac{{{x}^{4}}+{{x}^{5}}-{{x}^{8}}}{{{x}^{3}}}=x+{{x}^{2}}-{{x}^{5}}\] i.e., degree of the polynomial is 5.
