Question

1. Resolva as questões exponenciais a seguir:


a) $225^{3(x+1)}=15$

Answer 1

${225}^{3(x + 1)} = 15 \\ {15}^{2 \cdot3(x + 1)} = {15}^{1} \\ {\diagup\!\!\!\!15}^{6x + 6} = {\diagup\!\!\!\!15}^{1} \\ 6x + 6 = 1 \\ 6x = 1 - 6 \\ 6x = - 5 \\ \bf{x = - \frac{5}{6} }$

Espero ter ajudado! :)
