1)
2⁻³ = 1 / 2³ = 1/8,
2)
-3⁻³ = 1 / (-3)³ = -1/27,
3)
-1⁻²² = 1 / (-1)²² = 1/1 = 1,
4)
(2/5)³ = 2³ / 5³ = 8/125,
5)
0,02⁻³ = (1/5)⁻³ = (5/1)³ = 125,
6)
1,25⁻² = (5/4)⁻² = (4/5)² = 16/25,
7)
-4⁻³ = 1 / (-4)³ = -1/64,
8)
(-0,3)⁻² = (3/10)⁻² = (10/3)² = 100/9 = 11 1/9,
9)
(- 2 1/2)⁻³ = (-5/2)⁻³ = (-2/5)³ = -8/125,
10)
(-2,25)⁻¹ = (-9/4)⁻¹ = (-4/9)¹ = -4/9,
11)
-(-2,3)⁻¹ = -(-23/10)⁻¹ = -(-10/23)¹ = -(-10/23) = 10/23,
12)
-(-2 1/3)⁻² = -(-7/3)⁻² = -(-3/7)² = -(-9/49) = 9/49
