Q3 of 6 Page 116

Write cubes of all natural numbers b/w 1 to 10 and observe pattern.

13 = 1 × 1 × 1 = 1


23 = 1 × 1 × 1 = 8


33 = 1 × 1 × 1 = 27


43 = 1 × 1 × 1 = 64


53 = 1 × 1 × 1 = 125


63 = 1 × 1 × 1 = 216


73 = 1 × 1 × 1 = 343


83 = 1 × 1 × 1 = 512


93 = 9 × 9 × 9 = 729


103 = 10 × 10 × 10 = 1000
