Final answer:
To simplify the expression 1+(16+b) using the associative property, group the numbers and apply the property twice. The simplified expression is 17 + b.
Step-by-step explanation:
To simplify the expression 1+(16+b) using the associative property, we first group the numbers together. Since addition is associative, it doesn't matter which two numbers we add first. We can either add 1 and 16 first or 16 and b first. Let's choose to add 16 and b first. So the expression becomes 1 + (16 + b).
Next, we can use the associative property again to group the remaining numbers. We add 1 and the sum of 16 and b. The result is 1 + 16 + b. Therefore, the simplified expression using the associative property is 17 + b.
