Solution for 2/3/n/n=54 equation: 


D( n )

n = 0

n = 0

n = 0

n in (-oo:0) U (0:+oo)

((2/3)/n)/n = 54 // - 54

((2/3)/n)/n-54 = 0

2/3*n^-2 = 54 // : 2/3

n^-2 = 81

-2 < 0

1/(n^2) = 81 // * n^2

1 = 81*n^2 // : 81

1/81 = n^2

n^2 = 1/81 // ^ 1/2

abs(n) = 1/9

n = 1/9 or n = -1/9

n in { 1/9, -1/9 }
