Preciso para hoje por favor!!!!

Answer 1

Resposta:

a) 20 – (1⁴. 6 + 2³) =

20-(1.6+8)

20-(6+8)

20-14

6

b) (2⁴ – 3 . 4) : 2 + 5²: 5 =

(16-3.4):2+25:5

(16-12):2+5

4:2+5

2+5

7

c) 10²: 5² + 5⁰. 2² – 2³ =

100:25+1.4-8

4+4-8

8-8

0

d) {6² + 2 . [2³ + 2 . (3². 1³)] – 2⁵} . 5⁰ =

{6²+2.[2³+2.(9.1)]-2⁵}.5⁰

{6²+2.[2³+2.9]-2⁵}.5⁰

{6²+2.[8+18]-2⁵}.5⁰

{6²+2.26-2⁵}.5⁰

{36+52-32}.5⁰

{36+52-32}.5⁰

{88-32}.5⁰

56.5⁰

56.1

56

e) 55 – (3 . 2 + 1)2 + (4² + 3²) : 5² – 1⁶ =

55-(6+1).2+(16+9):5²-1⁶

55-7.2+25:5²-1⁶

55-14+25:25-1

55-14+1-1

41+1-1

42-1

41

2) Calcule o valor de A + B sabendo que:

A = (3 . 2 – 1)² e B = (2² + 1) . (5 + 2³)

A+B

(3.2-1)²+(2²+1).(5+2³)

(6-1)²+(4+1).(5+8)

5²+(4+1).(5+8)

25+5.13

25+65
