Question

tudo sobre logaritimos

 

Answer 1

log(a)b = c --> a^c = b
ex.: log(2)8 = 3 --> 2^3 = 8
log(a)a = 1
log(a)b^n = n.log(a)b
log(a)(x.y) = log(a)x + log(a)y
log(a)(x/y) = log(a)x - log(a)y
log(a)b = log(n)a / log(n)b
log 10 = log(10)10 = 1
log 100 = 2
log 1000 = 3 
log 10^-1 = -1
log 10^5 = 5
