Respostas
Para essa tarefa, precisamos resolver as potências:
1. a) 3^{-2}3
−2
= 1/3² = (1/3) x (1/3) = 1/9 = 0,11
b) 2^{-3}2
−3
= 1/2³ = (1/2) x (1/2) x (1/2) = 1/8 = 0,125
c) 10^{-1}10
−1
= 1/10 = 0,1 (para expoente negativo, basta escrever a base da potência em forma de fração e aplicar suas propriedades)
d) 6^{-3}6
−3
= 1/6³ = (1/6) x (1/6) x (1/6) = 1/216
2. a) (2/6)^{-2}(2/6)
−2
= (6/2)² = 6²/2² = 36/4 = 9
b) (3/5)^{-1}(3/5)
−1
= 5/3¹ = 5/3 = 1,66
c) (2/3)^{-3}(2/3)
−3
= (3/2)³ = 3³/2³ = 27/8 = 3,375
3). a) (-8)^{-2}(−8)
−2
= (1/-8)² = (1/-8) x (1/-8) = 1/64
b) (4)^{-3}(4)
−3
= 1/4³ = 1/4 x 1/4 x 1/4 = 1/64
c) (-3/7)² = (-3/7) x (-3/7) = 9/49
d) (2/4)^{-4}(2/4)
−4
= (4/2)^{4}(4/2)
4
= 4/2 x 4/2 x 4/2 x 4/2 = 256/16 = 16
e) (3/5)^{-5}(3/5)
−5
= (5/3)^{5}(5/3)
5
= 5/3 x 5/3 x 5/3 x 5/3 x 5/3 = 3125/243 = 12,86
f) (-12/13)^{-1}(−12/13)
−1
= (13/-12) = - 1,08
g) (7/9)^{-2}(7/9)
−2
= (9/7)² = (9/7) x (9/7) = 81/49
h) (6)^{-4}(6)
−4
= (1/6)^{4}(1/6)
4
= 1/6 x 1/6 x 1/6 x 1/6 = 1/1296
e) 10^{-2}10
−2
= 1/10² = 1/10 x 1/10 = 1/100 = 0,01
f) 2^{-5}2
−5
= 1/2^{5}1/2
5
= 1/2 x 1/2 x 1/2 x 1/2x 1/2 = 1/32 = 0,03
g) 100^{-1}100
−1
= 1/100¹ = 1/100 = 0,01
i) 1^{-18}1
−18
= 1/1^{18}1/1
18
= 1
d) (-4/5)^{-3}(−4/5)
−3
= (5/-4)³ = (125/-64) = -1,95
e) (-3/9)^{-2}(−3/9)
−2
= (9/-3)² = (81/-9) = -9
f) (-6/7)^{-3}(−6/7)
−3
= (7/-6)³ = (343/-216) = -1,59
