Answer 2

Answer:

7 is not the cube of a rational number

Step-by-step explanation:

0³ = 0 × 0 × 0 = 0

1³ = 1 × 1 × 1 = 1

2³ = 2 × 2 × 2 = 8

3³ = 3 × 3 × 3 = 27

4³ = 4 × 4 × 4 = 64

5³ = 5 × 5 × 5 = 125

6³ = 6 × 6 × 6 = 216

7³ = 7 × 7 × 7 = 343

8³ = 8 × 8 × 8 = 512

9³ = 9 × 9 × 9 = 729

10³ = 10 × 10 × 10 = 1000

so ,

here now

7³ = 7 × 7 × 7 = 343

therefore, 343 is not a rational number
