Question

find the least number which must be added to the following numbers to make them perfect squares: (1) 506900 (2) 4515600​

Answer 1

Answer:

1/

√506900

quotient= 711

next number of 711=712

(712)^2=506944

506944 -506900=44

thus 44 is the least number that must be added to 506900 to make it a perfect square.

2/

√4515600

quotient=2124

next number of 2124=2125

(2125)^2= 4515625

4515625-4515600= 25

thus 25 is the least number that must be added to 4515600 to make it a perfect square.
