savera kumari  (8 years ago) Best Solution

answer will be 3...
go with the options... (x^1 -27) not divisible by (x-3)
when we put the the value of n as 3, (x^3 - 27)/(x-3)
(x^3 - 3^3)/(x-3) as we know the formula of (a^3 -b^3) is (a-b)(a^2+ab+b^2) same way put the formula (x-3)(x^2+3x+3^2)/(x-3) so 3 will be the answer

n=3
-By using identity formula of cubes i.e. a^3-b^3=(a-b)*(a^2+a*b+b^2)
therefore, (x^3-27)/(x-3) can be expanded as
=(x^3-3^3)/(x-3)
=((x-3)*(x^2+3*x+3^2))/(x-3)
