Writhe the units digit of the cube of each of the ffolloiwng numbers:
31, 109, 388, 833, 4276, 5922, 77774, 44447, 125125125.

Answer 1

We know that if unit digit of a number n is
= 1, then units digit of its cube = 1
= 2,then units digit of its cube = 8
= 3,then units digit of its cube = 7
= 4,then units digit of its cube =4
= 5, then units digit of its cube = 5
= 6, then units digit of its cube =6
=7, then units digit of its cube = 3
= 8, then units digit of its cube = 2
= 9, then units digit of its cube = 9
= 0, then units digit of its cube = 0
Now units digit of the cube of 31 = 1
Units digit of the cube of 109 = 9
Units digits of the cube of 388 = 2
Units digits fo teh cube of 833 = 7
Units digits of te cube of 4276 = 6
Units digit of the cube of 5922 = 8
Units digit of the cube of 77774 =4
Units digit f the cube fo 44447 = 3
Units digit of the cube of 125125125 = 5
