Answer 2

Given:

i) 4096 (ii) 108 (iii) 392

(iv) 27000 (v) 64

1331

To Find :

Which of the given numbers are perfect cubes?

Solution :

1) 4096 (iv) 27000 (v) 64 (vi) 1331 are perfect cubes.

cube means we should multiply the number itself three times.

$= > {16}^{3} = 16 \times 16 \times 16 = 4096$

$= > {30}^{3} = 30 \times 30 \times 30 = 27000$

$= > {4}^{3} = 4 \times 4 \times 4 = 64$

$= > {11}^{3} = 11 \times 11 \times 11 = 1331$

Hence, 4096, 27000, 64 and 1331 are perfect cubes.
