1- Em que base de 81/16= 4?
2- Qual é o log de (x-2) base 4 = 1/2?

kjmaneiro Veja...

1)
$\log_x \frac{81}{16} =4 \\ \\ x^4= \frac{81}{16} \\ \\ x^4=( \frac{3}{2} )^4 \\ \\ x= \frac{3}{2} \mapsto~a~base$

2)
$\log_4(x-2)= \frac{1}{2} \\ \\ 4^{ \frac{1}{2} }=x-2 \\ \\ \sqrt{4} =x-2 \\ \\ 2=x-2 \\ \\ 2+2=x \\ \\ x=4$
