For what natural n is the number (5^(2*n+1))*(2^(n+2))+(3^(n+2))+(2^(2*n+1)) divisible by 19? I get that (19*(50^n + 12^n) + (50-19)(50^n +....+19^n). So it means that n can be any natural number? Or I did some mistake there?

Hello log (2 ^ t + t ^ 2-64) = t (1-log (5)) I put i = t with i ^ 2 = -1 So log (2 ^ i + i ^ 2-64) = i (1-log (5)) so log (2 ^ i-65) = i (1-log (5)) ln (2 ^ i-65) + i * ln (5) -i = ln (2 ^ i-65) + ln (5-i) = -i 0 ln (((2 ^ i-65) * 5 ^ i) = i therefore (2 ^ i-65) * 5 ^ i = exp (i) =...
