Log*subscript*(3x − 2) 4096 = 3 I got x= negative 6 is this correct??

Brut [27]

Remember

$log_a(b)=c$ translates to $a^c=b$
and
$log_a(b^c)=clog_a(b)$
so

4096=16^3
$log_{3x-2}(4096)=3$
$log_{3x-2}(16^3)=3$
$3log_{3x-2}(16)=3$
divide both sides by 3
$log_{3x-2}(16)=1$
translate
$(3x-2)^1=16$
3x-2=16
add 2 to both sides
3x=18
divide both sides by 3
x=6

Answer:

1/8

Step-by-step explanation:

Solving in steps:

x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
x/8(x-y) +y/8*(-(x-y))
x/8(x-y) - y/8(x-y) =
(x -y)/8(x-y) =
1/8

Answer is 1/8
