Question

(Tiradentes-2013)
$a = ( {0.3})^{ - 1} + ( {0.1})^{ - 2} + ( { - 1)}^{5}$

$b = 2( {0.3})^{2} \\ 2 - 1.4$

o quociente entre A e B é?​

Answer 1

Resposta:

$a = (0.3)^{-1} + (0.1)^{-2}+(-1)^{5}\\a=3,333+100+(-5)\\a= 98,333\\\\b=2(0.3)^{2}-1.4\\b= 0,09 - 1.4\\b = -1,31$

a/b = 98,333/(-1,31) = -75,06
