evaluate 3 × sup(2,4 1).
It seems like there might be a misunderstanding with the expression "3 × sup(2,4 1)” as written. Let’s try to clarify what this expression could mean and then evaluate it.
Understanding the Expression
-
sup: This typically stands for “supremum,” which is the least upper bound of a set. In mathematical terms, ( \sup(A) ) means the smallest number that is greater than or equal to every number in the set ( A ).
-
(2,4,1): This appears to be a set or list of numbers. The order would indicate that you’re finding the supremum of the numbers 2, 4, and 1.
-
3 × [expression]: Once we’ve determined what the expression inside the brackets equals, we will multiply the result by 3.
Step-by-Step Evaluation
-
Finding the Supremum of the Set ( {2, 4, 1} ):
- Look at the set: ( {2, 4, 1} ).
- The supremum, or the largest element, of this set is 4 because 4 is greater than the other numbers.
-
Multiply By 3:
- Now you take the supremum result, 4, and multiply it by 3.
- ( 3 \times 4 = 12 ).
Final Result
Thus, the evaluation of the expression ( 3 \times \sup(2, 4, 1) ) is:
Summary: The expression ( 3 \times \sup(2,4,1) ) evaluates to 12.
