Question

(a^n - b^n) is always divisible by (a - b). If n is-

(A) odd number
(B) even number
(C) natural number
(D) prime number​

Answer 1

Answer:

let b=0

now, we can write

${a}^{n} - {b}^{n}$

as

${a}^{n}$

and a-b = a (because we let b=0)

now a^n can be devided by a if a is natural number
