Odpowiedź:
a)
2³ = 2 * 2 * 2 = 8
(3/5)² = 3/5 * 3/5 = 9/25
(- 1)⁵ = (- 1) * ( - 1) * ( - 1) * ( - 1) * ( - 1) = - 1
(- 7)⁰ = 1
b)
(1 2/5)² = (7/5)² = 7/5 * 7/5 = 49/25 = 1 24/25
(- 2 1/2)² = (- 5/2)² = (- 5/2) * (- 5/2) = 25/4 = 6 1/4
- 1,2² = - (1,2)² = - (1,2 * 1,2) = - 1,44
- 4³ = - (4 * 4 * 4) = - 64
