Question

(3x-1)^3=-8/27

 

Answer 1

x/-15=-60/x

Answer 2

x/-15=-60/x

x²⁰¹²=2012

(3x-1)³=-8/27

-2/x=-x/8/25

(8x-1)²ⁿ=5²ⁿ

(x-2/3)³=(2/3)⁶

Answer 3

\(\left(3x-1\right)^3=-\frac{8}{27}\)

\(\left(3x-1\right)^3=\left(-\frac{2}{3}\right)^3\)

\(3x-1=-\frac{2}{3}\)

\(3x=-\frac{2}{3}+1\)

\(3x=-\frac{2}{3}+\frac{3}{3}\)

\(3x=-\frac{1}{3}\)

\(x=-\frac{1}{3}\div3\)

\(x=-\frac{1}{3}\times\frac{1}{3}\)

\(x=-\frac{1}{9}\)
