Question

namoral alguem me ajuda é muito rapido/ Resolva a equação log5(3x – 6 ) = – 1

Answer 1

Resposta:

Explicação passo-a-passo:

$log5(3x-6 ) = - 1\\\\(3x-6)=5^{-1}\\\\3x=\frac{1}{5} +6\\\\3x= \frac{31}{5} \\\\x\frac{\frac{31}{5} }3}\\\\x=\frac{31}{5}*\frac{1}{3}= \frac{31}{15}$

Answer 2

Oie, Td Bom?!

$log_{5}(3x - 6) = - 1$

$3x - 6 = 5 {}^{ - 1}$

$3x - 6 = \frac{1}{5}$

$3x = \frac{1}{5} + 6$

$3x = \frac{1 + 30}{5}$

$3x = \frac{31}{5}$

$x = \frac{31}{5} \div 3$

$x = \frac{31}{5} \: . \: \frac{1}{3}$

$x = \frac{31}{15}$
