is the answer hope it's helpful

Answer 2

Step-by-step explanation:

No, by Euclid Lemma, b=aq+rm 0≤r<a0≤r<a

Here, b is any positive integer a=3,b=3q+rfora=3,b=3q+rfor0 le r lt 3So,thisμstbe∈theformSo,thisμstbe∈theform3q,3q+1 or 3q+2Now,Now,(3q)^(2) =9q^(2)=3m[here,[here,m=3q^(2)]and]and(3q+1)^(2)=9q^(2)+6q+1=3(3q^(2)+2q)+1=3m+1[where,[where,m=3q^(2)+2q]Also,]Also,(3q+2)^(2)=9q^(2)+12q+4=9q^(2)+12q+3+13=(3q^(2)+4q+1)3m=1[here,[here,m=3q^(2)+4q+1]`

Hence, square of a positive integer is of the form 3q+1
