Answer 1

Resposta:

$1,04.10^{16}$

Explicação passo-a-passo:

$\frac{7,8.10^{-3}.5,4.10^{4}}{8,1.10^{-7}.5.10^{-8}} =\frac{7,8*5,4}{8,1*5}*\frac{10^{-3}*10^{4}}{10^{-7}*10^{-8}} =\frac{42,12}{40,5}*\frac{10^{(-3+4)}}{10^{(-7-8)}} =1,04*\frac{10^{1}}{10^{-15}}=1,04*10^{1}*10^{15}=1,04*10{^1+15}=1,04.10^{16}$
