Step-by-step explanation:

Answer 2

$\boxed{\huge{\red{Answer}}}$

1. $\boxed{\huge{\sqrt{506900}}}$

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. $\boxed{\huge{\sqrt{4515600}}}$

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.
