Question

Accepted Answer

Step 1: Find the remainder when 9^20 is divided by 4.

Since 9 mod 4 = 1 (because 9 = 4*2 + 1),

Therefore, 9^20 mod 4 = (9 mod 4)^20 = 1^20 = 1.

Step 2: Add 2 to the result:

(9^20 + 2) mod 4 = (1 + 2) mod 4 = 3 mod 4 = 3.

Hence, the remainder when 9^20 + 2 is divided by 4 is 3.
