Answer 2

To solve the given expression, let's break it down step by step:

1. Start by simplifying the expression inside the parentheses: 714 - 649 = 65

2. Multiply the result from step 1 by 3: 3 * 65 = 195

3. Divide 95 by 19: 95 / 19 = 5

4. Divide 68 by 2: 68 / 2 = 34

5. Multiply the results from steps 3 and 4: 5 * 34 = 170

6. Multiply 38 by 7: 38 * 7 = 266

7. Now, substitute the results from steps 2, 5, and 6 back into the original expression: 195 * 7 - 170 + 266

8. Perform the remaining calculations: 195 * 7 = 1365 1365 - 170 = 1195 1195 + 266 = 1461

Therefore, the value of the expression 3*(714-649)*7-(95:19)*(68:2)+38*7 is 1461.
