POR FAVOR ME AJUDEM! Calcule

1) ⅘ - 2/10 + 1/5 • ⅔ + (⅕)2 =

2) (⅕)² + ⅔= (⅕)² - 1/25 =

Answer 1

Resposta:

Explicação passo-a-passo:

1) ⅘ - 2/10 + 1/5 • ⅔ + (⅕)2 =

1/5 * 2/3 = 2/15

1/5 * 2 = 2/5

4/5 - 2/10 + 2/15 + 2/5 (mmc entre 5, 10 e 15 = 30)

(24 - 6 + 4 + 12)/30

34/30 = 17/15

2) (⅕)² + ⅔= (⅕)² - 1/25

1/25 + 2/3 = 1/25 - 1/25

1/25 + 2/3 = 0 (mmc entre 3 e 25 = 75)

(3 + 50)/75

53/75
