What are the digits in the units place of the cubes of 1,2,3,4,5,6,7,8

1.	What are the digits in the units place of the cubes of 1,2,3,4,5,6,7,8,9,10? Is impossible to say that a number is not a perfect cube by looking at the digit in the units place of the given number, just like you did for squares?
Answer» 13=1 23 = 8 33 = 27 4³= 64 5³ = 125 6³ = 216 7³ = 343 8³ = 512 9³ = 729 10³ = 1000 ∴ It is not possible to say whether the number is a perfect cube (or) not looking at the digit in unit place.

Answer»

13=1

23 = 8

33 = 27

4³= 64

5³ = 125

6³ = 216

7³ = 343

8³ = 512

9³ = 729

10³ = 1000

∴ It is not possible to say whether the number is a perfect cube (or) not looking at the digit in unit place.
