Find the values of exponential numbers.
(1) 44
(2) 25
(3) 64
(4) (−3)4
(5) (−5)3
(1) 44 = 4 × 4 × 4 × 4 = 256
∴44 = 256
(2) 25 = 2 × 2 × 2 × 2 × 2 = 32
∴25 = 32
(3) 64 = 6 × 6 × 6 × 6 = 1296
∴ 64 = 1296
(4) (−3)4 = (−3) × (−3) × (−3) × (−3) = +81
∴ (−3)4 = +81
(5) (−5)3 = (−5) × (−5) × (−5) = −125
∴ (−5)3 = −125
