dupa ce spargem parantezele obtinem:
[tex]E = a^{3/3} - a^{2/3} * b^{1/3} + a^{1/3} * b^{2/3} + a^{2/3} * b^{1/3} - a^{1/3} * b^{2/3} + b^{3/3}[/tex]
dupa ce se simplifica termenii (+ si -) avem:
[tex]E = a^{3/3} + + b^{3/3} [/tex]
iar apoi se simplifica fractiile:
[tex]E = a + b [/tex]
Simpatic :)
