What could be the possible ‘one’s’ digits of the square root of each of the following numbers? ii. 99856

Dear Student

We know that the unit’s digit of the square of a number having digit as unit’splace 6 is 6 and also 4 is 6 [62=36 and 42=16, both the squares have unit digit 6].∴ Unit’s digit of the square root of number 99856 is equal to 6.

Thanks
