    Explanation:

    We need to find the value of following expression :

    \dfrac{(6.67 \times 10^{-11})(5.97 \times 10^{24})}{(6.38 \times 10^6)^2}

    Firstly, solving the numerator of the above expression :

    =\dfrac{39.8199\times 10^{-11+24}}{40.7044\times 10^{12}}\\\\=\dfrac{39.8199\times 10^{13}}{40.7044\times 10^{12}}\\\\=9.7827

    Rounding off the result = 9.78

    In scientific notation : 9.78\times 10^0

    The value of a = 9.78 and k = 0.
