X to thelearn power n minus 27 is divisible by x minus 3 when n is equalbetter

Answer»

Answer:

N = 3

Step-by-step explanation:

So,

your question is

X power n - 27 divisible by x-3 when n is equal to

\frac{x^n -27}{x-3}

(x-3) is only divisible when in numerator there is (x-3)

and SINCE 27 is perfect cube

So,

By using identity formula of cubes

a³- b³ = (a-b)(a²+ab+b²)

(x-3) is only divisible when in numerator there is (x-3)

so we can write

\frac{x^3 -(3)^3}{x-3}
