    Answer:

    D: 9.041 × 10^(10)

    Step-by-step explanation:

    The correct expression is;

    (9.84 × 10^(10)) – (7.99 × 10^(9))

    To subtract this, we need to ensure that both terms have the same powers.

    Thus, (7.99 × 10^(9)) = (0.799 × 10^(10))

    Lets now solve;

    >> (9.84 × 10^(10)) – (0.799 × 10^(10))

    Collecting like terms we have;

    (9.84 – 0.799) × 10^(10)

    >> 9.041 × 10^(10)
