Question

O resultado da operação (3/4ab² - 4/3a²b) +(5/8 ab² - 5/6 a²b) é:

Answer 1

3/4ab²+5/8ab²-4/3a²b-5/6a²b
6/8ab²+5/8ab²-8/6a²b-5/6a²b
11/8ab²-3a²b

Answer 2

(3/4 ab²      - 4/3 a²b)      + (5/8 ab²     - 5/6 a²b) =
 3/4 ab² + 5/8 ab² - 4/3 a²b - 5/6 a²b = 
 2.3/8 ab² +5/8 ab² - 2.4/6 a²b - 5/6 a²b =
 6 + 5ab²/8 - 8 -5 a²b/6 =
 11/8 ab² -13/6 a²b
