Question

which of the following are the cubes of odd numbers: a)125 b)512 c)729 d)1000 e)2197​

Answer 1

We know that,

The cube of an even number is even and the cube of an odd number is odd.

Hence,

125,2197,6859 are cubes of an odd number and 512,1000,4096 are cubes of an even number.

Answer 2

Answer:

a, c, e

Step-by-step explanation:

125 = 5^3

512 = 8^3

729 = 9^3

1000 = 10^3

2179 = 13^3

therefore a, c and e are cubes of odd numbers.

Another approach will be that cubes of odd numbers is odd and even numbers is even. So a, c and e are odd numbers therefore a, c and e are cubes of odd numbers
