Final answer:
The simplified form of the expression (6-2·65)-3 is -127. This is determined by first performing the multiplication within the parentheses followed by the subtraction.
Step-by-step explanation:
The student is asking for the simplified form of the mathematical expression (6-2·65)-3. To solve this, we first perform the multiplication within the parentheses, which is 2·65, and then subtract the product from 6. Afterward, we subtract 3 from the result. Let's break it down step by step:
Multiply 2 and 65 to get 130: 2·65 = 130.
Subtract 130 from 6: 6 - 130 = -124.
Subtract 3 from -124 to get the final answer: -124 - 3 = -127.
Therefore, the simplified form of the expression (6-2·65)-3 is -127.
