Question

resolva as expressões a-2/3+2(3/2)²-(-4/3)²

-5/4*3/7+1/3

2/3/3/5+5/4-2

Answer 1

Resposta:

Explicação passo a passo:

-2/3+2(3/2)²-(-4/3)² =

-2/3 + 2(9/4) -(16/9) =

-2/3 + 18/4 - 16/9

-2/3 + 9/2 - 16/9 =

mmc entre 2 3 e 9 = 18

(-12+81-32)/18 =

37/18

-5/4 * 3/7 + 1/3 =

-15/28 + 1/3 =

mmc entre 3 e 28 = 84

(-45 + 28)/84 =

-17/84

2/3 / 3/5 + 5/4 - 2 =

2/3 * 5/3 + 5/4 + 2 =

10/9 + 5/4 + 2 =

mmc entre 4 e 9 = 36

(40+45+72)/36 =

157/36
