AJUDAAAAAAAAAAAAAAAAAAAAAA POR FAVORRRR​

Answer 1

1)

a) 4^-2 = 1/4^2 = 1/16

b) (-3)^-4 = (1/3)^4 = 1/81

c) (2/5)^-1 = (5/2)^1 = 5/2

d) (1/3)^-3 = (3/1)^3 = 27

e) (5/4)^-3 = (4/5)^3 = 64/125

2)

a) (-1/3)^-2 = (3/1)^2 = 9

b) (-2/5)^-3 = (-5/2)^3 = - 125/8

c) (-2)^-5 = (-1/2)^5 = - 1/32

d) (-5)^-3 = (-1/5)^3 = - 1/125

e) 4^-3 = 1/4^3 = 1/64

f) 5^-1 = 1/5^1 = 1/5

3)

a) (-4)^2 - 3 = 16 - 3 = 13

b) 1 + (-2)^3 = 1 - 8 = - 7

c) - 2 + (-5)^2 = - 2 + 25 = 23
