Use euclids division lemma to show that the square of any poistive integer is of the form 3p. ,3p+1

Answer» LET US take, 'X'= 3q , 3q+1, 3q+2
when, x=3q
x2 = (3q) 2
x2 = 9q2
x2 = 3(3q2)
we see that 3q2= m
so we have done the first equation 3m

when , x=3q+1
x2= (3q+1)2
[since, (a+b)2 = a2+2ab+b2]
x2= 9q+6q+1
x2= 3(3q+2q)+1
in this we see that 3q+2q= m
THEREFORE, this SATISFY the equation m+1
