Question

0,00001 . (0,01)² . 10³ / 0,001 - 10² . (0,1)^-3 / 10^8

a)um centésimo
b) zero
c)um decimo
d)um

Answer 1

Resolvendo
(10^-5x10^-4x10³/10^-3)- (10²x10³/10^8)
(10^-5x10^-4x10³x10³)-(10^5x10^-8)
10^-3 -10^-3=0
a resposta é a letra b

Answer 2

R: Letra B

veja

$0,00001.(0,01)^2.10^3:0,001-10^2.(0,1)^-^3:10^8=$

$10^-^5.(10^-^2)^2.10^3: 10^{-3} -10^2.(10^-^1)^-^3:10^8=$

$10^{-5} . 10^{-4} .10^3: 10^{-3} -10^2.10^3:10:8=$

$10^{-5-4+3} : 10^{-3} - 10^{2+3-8} =$

$10^{-6-(-3)} - 10^{-3} =$

$10^{-6+3} - 10^{-3} =$

$10^{-3} - 10^{-3} =$

$10^{-3} - 10^{-3} =0$
