Question

Resolva as expressões

Answer 1

1) 7² - (2.5 +1)^0 + [2^6+(-3)^4-(2¹-6^0):[(-2)^4-(-2)³]
49-1+ 144:24
48+6
54 => 1954

2) (2³)² + 3^7-².³ - (-3)^7 : 9²
64+3+2187:81
67+27
94 => 1994

Answer 2

Suíça:

7² – (2 · 5 + 1)⁰ + [2⁶ + (-3)⁴ – (2¹ – 6⁰)] ÷ [(-2)⁴ – (-2)³] =

7² – (2 · 5 + 1)⁰ + [2⁶ + -3⁴ – (2¹ – 6⁰)] ÷ (-2⁴ – -2³) =

7² – (2 · 5 + 1)⁰ + [2⁶ + -3⁴ – (2 – 6⁰)] ÷ (-2⁴ – -2³) =

7² – (2 · 5 + 1)⁰ + [2⁶ + -3⁴ – (2 – 1)] ÷ (-2⁴ – -2³) =

7² – (2 · 5 + 1)⁰ + [2⁶ + -3⁴ – (2 – 1)] ÷ (16 – -2³) =

7² – (2 · 5 + 1)⁰ + [2⁶ + -3⁴ – (2 – 1)] ÷ (16 – -8) =

7² – (10 + 1)⁰ + [2⁶ + -3⁴ – (2 – 1)] ÷ (16 – -8) =

7² – 11⁰ + [2⁶ + -3⁴ – (2 – 1)] ÷ (16 – -8) =

7² – 11⁰ + [2⁶ + -3⁴ – 1] ÷ (16 – -8) =

7² – 11⁰ + [2⁶ + -3⁴ – 1] ÷ 24 =

7² – 11⁰ + [64 + -3⁴ – 1] ÷ 24 =

7² – 11⁰ + [64 + -81 – 1] ÷ 24 =

7² – 11⁰ + [17 – 1] ÷ 24 =

7² – 11⁰ + 16 ÷ 24 =

49 – 11⁰ + 16 ÷ 24 =

49 – 1 + 16 ÷ 24 =

49 – 1 + 0.666666667 =

48 + 0.666666667 =

48.6666667

EUA:

(2³)² + 3⁷ ⁻ ² * ³ – (-3)⁷ ÷ 9² =

(2³)² + 3⁷ ⁻ ² * ³ – -3⁷ ÷ 9² =

8² + 3⁷ ⁻ ² * ³ – -3⁷ ÷ 9² =

64 + 3⁷ ⁻ ² * ³ – -3⁷ ÷ 9² =

64 + 3⁷ ⁻ ⁶ – -3⁷ ÷ 9² =

64 + 3¹ – -3⁷ ÷ 9² =

64 + 3 – -3⁷ ÷ 9² =

64 + 3 – -2187 ÷ 9² =

64 + 3 – -2187 ÷ 81 =

64 + 3 – -27 =

67 – -27 =

94
