What least number must be added to
7344 and 6203 to make it a perfect
square?
Answers
Step 1 : Write down the numbers as from the question.
We have :
7344
6203
Step 2 : Get their square roots so as to make the correct estimates.
Square root of 7344 = 85.697
Square root of 6203 = 78.759
Step 3: Identify the upper limit and the lower limits of the square roots.
85.697 : 85 and 86
78.759 = 78 and 79
Step 4 : Get the squares of the upper and lower limits in each case.
85² = 7225 86² = 7396
78² = 6084 79² = 6241
Step 5 : Since we are adding a number to the original numbers, the squares must be greater than the initial number.
We therefore take the square of the upper limit.
For 7344 we take 7396 and for 6203 we take 6241
Step 6:We now get the smallest numbers by subtraction.
7396 - 7344 = 52
6241 - 6203 = 38
