Question
The image contains a mathematical exercise involving modular arithmetic in \( \mathbb{Z}_7 \). The task is to evaluate each expression under modulus 7 and select the correct result from a dropdown menu. The expressions and potential answers are as follows: 1. \( 3 - (2 \times 5) \) 2. \( 2 \times 3 \times 4 \) 3. \( 5 \times 3 \) 4. \( 3 + 4 + 5 \) 5. \( 3^2 + 4^2 \) The possible answers provided for each expression are: - 1 - 2 - 3 - 4 - 5 - 6 - 0 The task is to find the correct result of each expression in \( \mathbb{Z}_7 \) (i.e., how the result would be represented under modulus 7) and choose from the provided options.
