It is known that 3 ^ n + M can be divided by 13. Try to explain that (3 ^ n + 3) + M can also be divided by 13 It is known that 3 ^ n + M can be divided by 13. Try to explain that (3 ^ n + 3) + M can also be divided by 13 Change to: It is known that the power of N + m of 3 can be divided by 13. Let's explain that the power of N + 3 of 3 can also be divided by 13

It is known that 3 ^ n + M can be divided by 13. Try to explain that (3 ^ n + 3) + M can also be divided by 13 It is known that 3 ^ n + M can be divided by 13. Try to explain that (3 ^ n + 3) + M can also be divided by 13 Change to: It is known that the power of N + m of 3 can be divided by 13. Let's explain that the power of N + 3 of 3 can also be divided by 13


3^(n+3)+m=27*3^n+m=26*3^n+(3^n+m)
Because 3 ^ n + M can be divided by 13, 26 * 3 ^ n + (3 ^ n + m) = 3 ^ (n + 3) + M can be divided by 13
