Question

3) Find the least no which must be added to 6235 to obtain a perfect square.Also find the square root of the number so obtained.​

Answer 1

Step-by-step explanation:

78

          ---------

7 |       62 03 

           49

          ----------

148 |   13 03

           11 84

          -----------

             19

          -----------

78^2 = 6084.

We observe that 78^2 < 6203.

79^2 = 6241.

We observe that 79^2 > 6203.

Hence the number to be added to 6203 is 6241 - 6203 = 38.

6203 + 38 = 3241

                   = 79 * 79

                   = 79.

Therefore 38 should be added to6203 to obtain a perfect square.

The same steps but change the number alone.I am writing like this bcoz then only you will not copy and you can understand.
