$\frac{28}{10^{10}}$ $28/10^10$

$(0.4 \times 10^{- 6}) (0.7 \times 10^{- 2})$ $(0.4xx10^-6)(0.7xx10^-2)$

$= (\frac{4}{10} \times 10^{- 6}) \times (\frac{7}{10} \times 10^{- 2})$ $=(4/10xx10^-6)xx(7/10xx10^-2)$

$= (\frac{4}{10} \times \frac{1}{10^{6}}) \times (\frac{7}{10} \times \frac{1}{10^{2}})$ $=(4/10xx1/10^6)xx(7/10xx1/10^2)$

$= (\frac{4}{10^{7}}) \times (\frac{7}{10^{3}})$ $=(4/10^7)xx(7/10^3)$

$= \frac{28}{10^{10}} = 0.0000000028$ $=28/10^10=0.0000000028$
