1)none
2)6
3)0
4) 7
Read Solution (Total 9)
-
- put x=0
so f(x)=1
f(x^7)=1
1/1=0
so 0 is answer - 10 years agoHelpfull: Yes(3) No(5)
- given: f(x)=1+x+x^2+x^3+x^4+x^5^+x^6
let x=1
i.e : f(1)=1+1+1+1+1+1+1=7
f(x^7)=(1)+(1)+(1^14)+.... =7
so, f(x^7)/f(x)=7/7=1
answer is : 1 - 10 years agoHelpfull: Yes(3) No(8)

- By substituting the different values of x. The numerator will be the multiples of denominator. Thus the quotient remains changing, but remainder will be constant.
i.e remainder is 0. - 10 years agoHelpfull: Yes(0) No(0)
