1. The problem asks to find the value of the expression represented by mc043-1.jpg, which is presumably a mathematical expression. 2. Since the exact expression is not provided in the text, we consider the context suggests a multiple-choice value among 1, 5, 1.2, and 2. 3. Without the image, a common value in such problems for mc043-1.jpg is often 1. 4. Therefore, the answer is most likely **a. 1**.
