Answer 1

QUESTION :

If n is any prime number and a' is divisible by n, then n will also divide a. Justify. !

Step-by-step explanation:

Let n = 3, a = 9

$\implies {a}^{2} = {9}^{2}$

$\implies \: {a}^{2} = 81$

$\bold h \bold e \bold r \bold e \: \frac{81}{3} = 27$

n divides a²

$now \: \frac{9}{3} = 3$

SO, HERE "n" also divides a.
