1. The problem is to understand why the number 6 can be expressed as the pair (4,1). 2. This likely refers to expressing 6 as a sum of squares or a similar decomposition. 3. One way to express 6 is as $4 + 1 + 1$, but since the question is about (4,1), let's consider the sum of squares: $4 = 2^2$ and $1 = 1^2$. 4. So, $6 = 2^2 + 1^2 + 1^2$ is one way, but if the question is about the pair (4,1), it might mean $6 = 4 + 1 + 1$ or $6 = 4 + 1 + 1$. 5. Alternatively, if the question is about coordinates or factors, 6 can be factored as $2 \times 3$, but that doesn't give (4,1). 6. Without more context, the best explanation is that 6 is decomposed into $4 + 1 + 1$, and the pair (4,1) represents part of this decomposition. 7. If the question is about the Euclidean algorithm or coordinate pairs, please provide more context.
