Answer 1

a) 3⁻¹ = (1/3)¹ = 1/3
5⁻² = (1/5)² = 1/25
2⁻³ = (1/2)³ = 1/8
b) (7/11)⁻¹ = (11/7)¹ = 11/7
(1/3)⁻² = (3/1)² = (9/1) = 9
(3/4)⁻² = (4/3)² = 16/9
c) (2,5)⁻¹ = (25/10)⁻¹ = (10/25)¹ = 10/25
(0,4)⁻² = (4/10)⁻² = (10/4)² = 100/16
(1,25)⁻¹ = (125/100)⁻¹ = (100/125)¹ = 100/125 = 4/5
d) (-10)⁻⁵ = (-10/1)⁻⁵ = (-1/10)⁵ = -1/100000
(-4)⁻² = (-4/1)⁻² = (-1/4)² = 1/16
(-2)⁻³ = (-2/1)⁻³ = (-1/2)³ = -1/8
e) (-2/3)⁻² = (-3/2)² = 9/4
(-1/5)⁻³ = (-5/1)³ = -125/1 = -125
(-3  1/3)⁻⁴ = (-10/3)⁻⁴ = (-3/10)⁴ = 81/10000
f) (-1,2)⁻¹ = (-12/10)⁻¹ = (-10/12)¹ = (-5/6)¹ = -5/6
(-0,1)⁻⁵ = (-1/10)⁻⁵ = (-10/1)⁵ = -100000/1 = -100000
(-0,02)⁻⁴ = (-2/100)⁻⁴ = (-100/2)⁴ = 100000000/16 = 6250000

Mam nadzieję, że pomogłam ;))
