(1/9) x = √27
(1/3²) x = √3³
x* 3^-2 = 3^³/2
x = (3^³/2) / (3^-2)
x = 3^(3/2+2)
x = 3^(3/2+4/2)
x = 3^(7/2)
ou
x = √2187

(1/9)x = √27
x = 9√(3^2 . 3)
x = 9 . 3 √3
x = 27√3

x/9 = √27
x/9 = √9 x (√3)
x/9 = 3√3
x = 9 (3√3)
x = 27√3
Só no caso de vc precisar de um resultado com o radical.

[(1/9) x]² = (√27)²
Simplificando:
1/81x² = 27
x² = 27 : 1/81
x² = 2187
x = \/2187
x = 46, 765...
