Question

Use Euclid's division lemma to show that the square of any positive integer is either of
the form 3m or 3m+1 for some integer m. ​

Answer 1

Answer:

let a be My positive integer then, by euclid division lemma a is of the form of 3q or 3q+1 for some integer

Step-by-step explanation:

now,. a=3q.

Answer 2

Answer:

let be a is any positive integer b = 3

By Euclid's division lemma

a = bq + r

r = 0,1,2

putting r = 0

a = 3q + r. [ b = 3 ]

a = 3q + 0

a = 3q

Squaring on both sides

After it.
