[tex] {9}^{16} = ( {3}^{2} )^{16} = {3}^{32} [/tex]

[tex] {27}^{11} = ( {3}^{3} )^{11} = {3}^{33} [/tex]

[tex] {3}^{32} + {3}^{33} = {3}^{32} \times (1 + 3) = {3}^{32} \times {2}^{2} = (2 \times {3}^{16} )^{2} [/tex]

Adică, pătrat perfect.

9*9*9*9*9*9*9*9*9*9*9*9*9*9*9*9*9= 1,215766545906e19
27*27 *27*27*27*27*27*27*27*27*27*27= 350.277.500.542.221
