Question

Ajutor îmi dă profa 2 daca nu fac asta

Answer 1

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