What is the digit in the unit place of 251?a)2b)8c)1d)4Correct answer...
The digit in the unit's place of 251 is equal to the remainder when 251 is divided by 10.
25 =32 leaves the remainder 2 when divided by 10.
Then 250 = (25)10 leaves the remainder 210 =(25)2 which in turn leaves the remainder 22= 4
Then 251= 250x 2, when divided by 10, leaves the remainder 4 x 2=8
