Answer:
Step-by-step explanation:
First we must use the long division method to find the remainder of this number....then....
the remainder must be subtracted from 825 to get the perfect square number.
Here goes the demo...
28
2 825
4
48 425
384
Remainder = 41
825-41=784
Least number is 41
√784=28.
In long division the dividend(I.e. 825 on this question)
must be taken in pairs from the last digit of that number and it had
to be divided with square root of numbers like√4=2. Number in pair
= 8 , 25 these are the pairs in this
question. Tata,that's it
Answer:
41 is the least number which must be subtracted from 825
Step-by-step explanation:
28×28= 784
825-784= 41
41 is the least number which must be subtracted from 825
