Question

let X1be a positive real number and for every integers n > 1 let Xn+1 = 1+X1 X2...Xn- Xn . lf X5= 43, what is the sum of digits of the largest prime factor of X6 ?​

Answer 1

Answer:

(x2+y2)(x+y). = x − y = 4. 3 . 2. Find (x + 1)(x2 + 1)(x4 + 1)(x8 + 1)···, where |x| < 1. Solution: Let S = (x + 1)(x2 + 1)(x4 + 1)(x8 + 1)··· ... Given that 7,999,999,999 has at most two prime factors, find its largest prime factor.
