Answer:
20/9
Step-by-step explanation:
Not sure what you need, but here is that simplified as much as possible:
(given) 7/3 + 3 (2/3 - 1/3)^2
(subtract) 7/3 + 3 (1/3)^2
(square) 7/3 + 3 (1/9)
(mixed number to improper fraction) 7/3 + 38/9
(changing 7/3 into 1/9s) 7/3 = 21/9
(expression) 21/9 + 38/9
(adding) 40/9
(simplify) 20/9
