Evaluate the following and write which number is the cube of which other number.
(1) 33 (2) 73
(3) 43 (4) 93
(5) 113 (6) 153
(1) The cube of 3 can be written as follows:
⟹ 3 × 3 × 3
⟹ 9 × 3
= 27
Hence 33 = 27.
(2) The cube of 7 can be written as follows:
⟹ 7 × 7 × 7
⟹ 49 × 7
= 343
Hence 73 = 343.
(3) The cube of 4 can be written as follows:
⟹ 4 × 4 × 4
⟹ 16 × 4
= 64
Hence 43 = 64.
(4) The cube of 9 can be written as follows:
⟹ 9 × 9 × 9
⟹ 81 × 9
= 729
Hence 93 = 729.
(5) The cube of 11 can be written as follows:
⟹ 11 × 11 × 11
⟹ 121 × 11
= 1331
Hence 113 = 1331.
(6) The cube of 15 can be written as follows:
⟹ 15 × 15 × 15
⟹ 225 × 15
= 3375
Hence 153 = 3375.
