Hi all,
I am trying to proof the following question.
If a is an integer, divisible by 4, then a is the difference of two perfect squares
now by the definition of divisibility if 4 divides a then there is a natural number k such that
a = 4k
Can someone how should I do it with direct proof by using if then technique?
