Answer:
To verify the commutativity of addition for the rational numbers 49 and -71, we need to check if \(49 + (-71)\) is equal to \((-71) + 49\).
Let's perform both additions:
\[ 49 + (-71) = 49 - 71 = -22 \]
\[ (-71) + 49 = -71 + 49 = -22 \]
Since \(49 + (-71) = -22\) is equal to \((-71) + 49 = -22\), we can conclude that addition is commutative for the rational numbers 49 and -71.
