Question

qual o log de 0,125 na base 16

Answer 1

Log16(0.125)=x 
Log16(1/8)=x 
Log2^4(2^-3) =x 
2^4^x=2^-3 
4x=-3 
X=-3/4

Answer 2

.
$\log_{16}0,125=x \\ \\ 16^x=0,125 \\ \\ 16^x= \frac{125}{1000} \\ \\ 16^x= \frac{1}{8} \\ \\ 16^x=8^{-1} \\ \\\not 2^{4x}=\not2^{-3} \\ \\ 4x=-3 \\ \\ x=- \frac{3}{4}$
