1. Yes, 8000 is a perfect cube.
8000 = 20 × 20 × 20
2. 2 is the number, when 4 is multipled by 2 it gives 8 which is a perfect cube.
3. cube root of 27 /64 = 3 /4 (27= 3³ and 64 = 4³)
4. cube root of 0.008 = 0.2
5. cube root of 27000 = 30
6. (10)³ - (4)³
(A-B)³ = (A-B) ( A² + B² + A*B)
(10-4)(100+16+40)
6*156
= 936
7. 4,096 = 2 × 2,048
2,048 = 2 × 1,024
1,024 = 2 × 512
512 = 2 × 256
256 = 2 × 128
128 = 2 × 64
64 = 2 × 32
32 = 2 × 16
16 = 2 × 8
8 = 2 × 4
4 = 2 × 2
2 = 2 × 1
4,096 can be written as a product of its prime factors in the following way:
4,096=2^12
∴cube root 4096= cube root (2)^12
we will make pairs of 3 times 2s and we will get 4 pairs
=2×2×2×2=16 answer is 16
8. cube root of 216 = 6 and 1728= 12
answer= 6 × 12=72
