8*(397-11)+ 3296:6

Let's solve the expression step by step.

1. Calculate the expression inside the parentheses: \(397 - 11 = 386\)

2. Multiply by 8: \(8 * 386 = 3088\)

3. Now, calculate the second part of the expression: \(3296 \div 6 = 549.33\) (approximately)

4. Finally, add the two results together: \(3088 + 549.33 \approx 3637.33\)

So, \(8*(397-11)+ \frac{3296}{6} \approx 3637.33\). If you want to keep it more precise, you can leave it as \(3637.33\).
