Question

qual a resposta de
log 0,0001=×
100

Answer 1

             S = log 0,001 + log 100
S = log 1/1000 + log 100
S = -3 + 2
S = -1
________________________
log 10 = 1
log 100 = 2
log 1000 = 3
________________________
OU

S = log (0,001 . 100)
S = log 0,1
S = log 1/10
S = log 10⁻¹
S = - log 10 ➜ -1

Answer 2

log0,01(0,0001) = log1/100(1/10000) 
log10^-2(10^-4) = x 
-4/-2 log10(10) = x 
2 log10(10) = x 
log10(10) = x/2 
10^x/2 = 10^1 

Cortando as bases: x/2 = 1 -> x = 2
