Answer 1

Resposta:

a) 3².4¹ - 2⁰+3¹.3².3³

3².4¹ - 2⁰+3⁶

9.4 - 1+729

36 - 1 + 729= 764

b) (-2)⁻⁶.8²+3⁰

(-1/2)⁶.8²+3⁰

1/64.64+1

64/64+1

1+1= 2

c) 6¹.3⁻²+4⁻¹-4.7⁰

6.(1/3)²+(1/4)-4.1

6.1/9+1/4-4.1

6/9+1/4-4

48+18-288/72

-222/72   simplificando por 6 = -37/12

d) (3/5)⁻².3⁴.5⁻²

(1/3/5)².3⁴.(1/5)²

1/9/25.3⁴.1/25

25/9.81.1/25

2025/225= 9

e) 8⁴.8³.8⁴:8⁸

8¹¹:8⁸= 8³ = 512

f) (3².3⁴/3⁵)+(2³+2⁴.2/2⁰)²

3⁶/3⁵+(2³+2⁵/2⁰)²

3⁶:3⁵+(2³+2⁵:2⁰)²

3¹+(2³+2⁵)²

3+(8+32)²

3+40²

3+1600= 1603
