Verified Solution

Answer & Solution

Correct Answer

(C) \(4\)

Step-by-step Solution

Detailed explanation

\((2023-2)^{3762}=2023 k _{1}+2^{3762}\) \(=17 k _{2}+2^{3762}(\) as \(2023=17 \times 17 \times 9)\) \(=17 k _{2}+4 \times 16^{940}\) \(=17 k _{2}+4 \times(17-1)^{940}\) \(=17 k _{2}+4\left(17 k _{3}+1\right)\) \(=17 k +4 \Rightarrow\) remainder \(=4\)
