Question

qual o logaritmo 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

$log_ba=x-->b^x=a\\\\\\log_{16}0,125=x \\\\ 16^x=0,125 \\\\ (2^4)^x=2^{-3} \\ 2^{4x}=2^{-3} \\\\ 4x=-3 \\\\ x= \frac{-3}{4} \\ \\ log_{16}0,125= \frac{-3}{4}\\\\\\Renato.$
