Question

2) Efetue

Calcule:

A) (7^3)^2 . 7-4

B) (11^3)^4
(11^2)^5

C) (3^2)^4 · 3
3^8

D) (13^3)^2 . (13-1)^3
13^7. (13^5)-1

Answer 1

Resposta:

A) 117.645

B) 8,14027494 . 10²²

c) 129.140.163

d) 371.293

Explicação passo-a-passo:

A) (7^3)^2 . 7-4 = 343² . 7 -4 = 117.649 -4 = 117.645

B) (11^3)^4(11^2)^5 = 1331⁴ . 121⁵ = 3.138.428.376.721 . 25.937.424.601 = 8,14027494 . 10²²

C) (3^2)^4 · 3 . 3^8 = 9⁴ . 3 . 6.561 = 6.561 . 3 . 6.561 = 129.140.163

D) (13^3)^2 . (13-1)^3 . 13^7. (13^5)-1 = 13⁶ . 13^-3 . 13⁷ . 13^-5 =

13⁵ = 371.293

Answer 2

Explicação passo-a-passo:

2) Calcule:

A)(7³)²•7-⁴= 7³×²•7-⁴= 7⁶•7-⁴=7⁶-⁴= 7²=49

B) (11³)⁴•(11²)⁵=11³×⁴•11²×⁵= 11¹²•11¹⁰ = 11¹²+¹⁰= 11²²

C) (3²)⁴•3•3⁸= 3²×⁴•3•3⁸= 3⁸•3•3⁸= 3⁸+¹+⁸= 3¹⁷

D) (13³)²•(13-¹)³•13⁷•(13⁵)-¹= 13³×²•13-³•13⁷•13-⁵= 13⁶-³+⁷-⁵=== = 13⁵
