Question

what kind of natural numbers cannot be written as difference of two perfect squares​

Answer 1

Step-by-step explanation:

Numbers such as 2,6,10 etc can't be made because these are made by multiplying an even by an odd. Thus, a number n can only be a difference of two squares if it has two factors of the form (a + b) and (a - b), where a + b \geq \sqrt{n} and a - b \leq \sqrt{n}.

Answer:

Numbers such as 2,6,10 etc can't be made because these are made by multiplying an even by an odd. Thus, a number n can only be a difference of two squares if it has two factors of the form (a + b) and (a - b), where a + b \geq \sqrt{n} and a - b \leq \sqrt{n}.
