Question

o logaritmo de 129 na base de 1/5.? eu quero a conta por favor

Answer 1

$log_{ \frac{1}{5} }129$ = log 129 / (log 1/5)

=log 129 /  (log 5⁻¹)  = log 129 / (- log 5)  = -log 129/ log 5 

≈ - 2,11059 / 0,69897  ≈  - 3,019572
 

Answer 2

Log129 base 1/5= X 

Log1/5 129=x
129=x^1/5
43.3=x^1/5
Log43.3=1/5.logX
X=Log129/Log1/5
X=2,11/-0,69 
X=-3,057
