c)9.103:3.10% =
d) 32. 10798.106

Answer 1

Resposta:

Explicação passo a passo:

$a) 7.10^{0} +2.10 = (7 + 2) . (10^{0} . 10^{1} ) = 9. (1 . 10) = 9 . 10 = 90$

$b) 2.10^{4} . 4.10^{1} = (2 . 4) . (10^{4} . 10^{1} ) = 8 . (10^{4+1} ) = 8 . 10^{5} = 8.100 000 = 800 000$

$c) 9.10^{3} : 3.10^{5} = (9 : 3) . (10^{3 - 5}) = 3.10^{-2} = 3 . 0,01 = 0,03$

b) 2.104X4.10"

c)9.103:3.10% =

d) 32. 10798.106
