(765+1835:5-97•6)•3

Let's solve the expression step by step.

1. Start with the innermost operations, in this case, the division and multiplication:

   • \( 1835 \div 5 = 367 \)
   • \( 97 \times 6 = 582 \)

2. Substitute these values back into the expression: \[ (765 + 367 - 582) \cdot 3 \]

3. Now perform the addition and subtraction inside the parentheses:

   • \( 765 + 367 = 1132 \)
   • \( 1132 - 582 = 550 \)

4. Now substitute this result back into the expression: \[ 550 \cdot 3 \]

5. Finally, perform the multiplication:

   • \( 550 \cdot 3 = 1650 \)

Thus, the value of the expression \( (765 + 1835 \div 5 - 97 \cdot 6) \cdot 3 \) is \( \boxed{1650} \).
