Question

Ajudasse aaaaa e pra agora por favoor

Answer 1

Resposta:

2) b) 2⁶/2

3) a) 1/144 b) 1/49 c) 1/64 d) 1/16 e) 1/64

f) 64/25 g) -8/27 h) 9/4 i) 32 j) -1/125

Explicação:

2) a) 2⁷/2¹ = 2^⁷-¹ = 2⁶

b) 2⁶/2 = 2^⁶-¹ = 2⁵

c) 2⁷×2^-¹ = 2^⁷+(-¹) = 2^⁷-¹ = 2⁶

d) (2³)² = 2^³×² = 2⁶

e) (2²)³ = 2^²×³ = 2⁶

3) a) 12^-² = (12/1)^-² = (1/12)² = 1²/12² = 1/144

b) 7^-² = (7/1)^-² = (1/7)² = 1²/7² = 1/49

c) 8^-² = (8/1)^-² = (1/8)² = 1²/8² = 1/64

d) 4^-² = (4/1)^-² = (1/4)² = 1²/4² = 1/16

e) 4^-³ = (4/1)^-³ = (1/4)³ = 1³/4³ = 1/64

f) (-5/8)^-² = (8/-5)² = 8²/(-5)² = 64/25

g) (-3/2)^-³ = (2/-3)³ = 2³/(-3)³ = 8/-27 = -8/27

h) (-2/-3)^-² = (-3/-2)² = (-3)²/(-2)² = 9/4

i) (1/2)^-⁵ = (2/1)⁵ = 2⁵/1⁵ = 32/1 = 32

j) (-5)^-³ = (-5/1)^-³ = (1/-5)³ = 1³/(-5)³ = 1/-125 = -1/125
