Question

Resolva as expressões abaixo: a) 4 2 – 10 + (23 – 5) = b) (72 – 5 2 ) + (52 – 3) = c) 32 x 23 + 22 x 52 = d) √121 - √36 + 25 - 3 3 - √100 = e) 62 ÷ 3 2 + 4 x 6 - √169 =

Ajudem.

Answer 1

Resposta:

a) 42 - 10 + ( 23 - 5 ) =

42 - 10 + 18 =

32 + 18 =

50

b) ( 72 - 52 ) + ( 52 - 3 ) =

20 + 49 =

69

c) 32 x 23 + 22 x 52 =

736 + 1.144 =

1.880

d) $\sqrt[]{121}$ - $\sqrt[]{36}$ + 25 - 33 - $\sqrt{100}$ =

11 - 6 + 25 - 33 - 10 =

5 + 25 - 33 - 10 =

30 - 33 - 10 =

- 3 - 10 = -13

e) 62 ÷ 32 + 4 x 6 - $\sqrt{169}$ =

62 ÷ 32 + 4 x 6 - 13 =

1,9375 + 4 x 6 - 13 =

1,9375 + 24 - 13 =

25,9375 - 13 =

12,9375
