Question

(X/2-1/3)^3=-27

 

Answer 1

\(\left(\frac{x}{2}-\frac{1}{3}\right)^3=-27\)

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

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

=> \(\frac{x}{2}=\frac{-8}{3}\)

=>  \(x=\frac{-16}{3}\)

 

Answer 2

(x/2-1/3)³=27

(x/2-1/3)³=3³

=> x/2-1/3=3

x/2=3+1/3

x/2=10/3

Answer 3

=>X/2 - 1/3 = -3

=>X/2 = -8/9

=>X = -16/9
