Open in App
Solution

(1) 63
It can be expressed and solved as:
63 = 6 × 6 × 6 = 36 × 6 = 216
∴ 63 is equal to 216.

(2) (−5)3
It can be expressed and solved as:
(−5)3 = (−5) × (−5) × (−5) = 25 × (−5) = −125
∴ (−5)3 is equal to −125.

(3) (−10)3
It can be expressed and solved as:
(−10)3 = (−10) × (−10) × (−10) = 100 × (−10) = −1000
∴ (−10)3 is equal to −1000.

(4) 143
It can be expressed and solved as:
143 = 14 × 14 × 14 = 196 × 14 = 2744
∴ 143 is equal to 2744.

(5) (−12)3
It can be expressed and solved as:
(−12)3 = (−12) × (−12) × (−12) = 144 × (−12) = −1728
∴ (−12)3 is equal to −1728.
