Solution
(1) (1)3 = 1 × 1 × 1 = 1
(2) (−2)3 = (−2) × (−2) × (−2) = −8
(3) (3)3 = 3 × 3 × 3 = 27
(4) (4)3 = 4 × 4 × 4 = 64
(5) (−5)3 = (−5) × (−5) ×(−5) = −125
(6) (23)3 = 23 × 23 × 23 = 8 × 8 × 8 = 512
(1) (1)3 = 1 × 1 × 1 = 1
(2) (−2)3 = (−2) × (−2) × (−2) = −8
(3) (3)3 = 3 × 3 × 3 = 27
(4) (4)3 = 4 × 4 × 4 = 64
(5) (−5)3 = (−5) × (−5) ×(−5) = −125
(6) (23)3 = 23 × 23 × 23 = 8 × 8 × 8 = 512
