Question

If x=11, then the value of x^5-12x^4-12x^3-12x^2-12x-1 is​

Answer 1

Answer:

-254

Explanation:

x = 11

x^5 - 12x^4 + 12x^3 - 12x^2 - 12x - 1

= x^5 - (11x^4+x^4 )+ (11x^3 + x^3 )- (11x^2+x^2) - (11x + x) - 1

= 11^5 - 11×11^4 - 11^4 + 11×11^3 + 11^3 - 11×11^2 - 11^2 - 11×11 -11 - 1

= -121-121-11-1

= -254
