It is often necessary to do calculations using scientific notation when working chemistry problems. For

practice, perform each of the following calculations.

$(9\mathrm{.}73{10}^5)(1\mathrm{.}00{10}^{-8})=$

$\frac{8\mathrm{.}66{10}^3}{2\mathrm{.}73{10}^{-4}-1\mathrm{.}00{10}^{-8}}=$

$\frac{(6\mathrm{.}10{10}^{-5})(9\mathrm{.}46{10}^6)}{8\mathrm{.}66{10}^3}=$
