The second value does not verify the equation.

You are right! ❤

Bro, listen to me. I am your big fan, but can u tell me why these equations are named after countries?

[@SALogics]

Because these questions are from international exam cometitions math olympiad ❤

Alternatively:
4/27 = is given.
4/27^1/4^1/3^1/3^1/3
=
1/729 = 0.00137…
Answer

[@trojanleo123]

x = 1/729

[@SALogics]

You are right! ❤

(x^⅓)+(x^½)=4/27
Let t=x^⅙ --> t²+t³=4/27
=(3/27)+(1/27)
=(1/9)+(1/27)
=(⅓)²+(⅓)³ --> t=⅓
As t=x^⅙ --> x=t⁶
=(⅓)⁶
=(⅓

Very nice trick! ❤
