Explicación paso a paso:
a) (5x10²) + (30x10²) = (5+30)x10² = 35x10² = 3,5x10³
b) [tex]- 7x10^{-5} + 1500000000x10^{-5} = (-7+1500000000)x10^{-5} =1499999993x10^{-5}[/tex]
c) (0,00012x10²) - (-0,5x10²) = (0,00012 - (--0,5)) x10² = 0,50012,9x10²
d) (3,8x10⁷ ) + (5,2x10³) = (38000x10³) + (5,2x10³) =
(38000+5,2)x10³=3805,2x10³
