Question

Find the least number which must be subtracted from 825 to get a perfect square number​

Answer 1

28×28= 784

825-784= 41

41 is the least number which must be subtracted from 825

Answer 2

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.
