Question

Qual o resultado da expressão

Answer 1

(2/1ab + 1/4 ab )+( 1/2 ab² - ab²/1) - (2/3 a²b + 1/6 a²b)=
(2/1) ab + (1/4 )ab =( 8ab + 1ab)/4 = (9/4) ab ******
(1/2)ab² - (1/1)ab² ( 1ab² - 2ab²)2  = ( - 1/2)ab²*****
( 2/3)a²b + (1/6) a²b = ( 4a²b + 1a²b)/6 = (5/6)a²b*****
reescrevendo
(9/4)ab + ( -1/2)ab² - ( 5/6)a²b =
(9/4)ab - (1/2)ab² - ( 5/6)a²b =
9ab /4 - 1ab²/2 - 5a²b/6 =
