1.3×[3.6×{7.5-3.5-5.5}] using bodmas rule

To simplify the expression 1.3 × [3.6 × {7.5 - 3.5 - 5.5}] using the BODMAS rule (also known as PEMDAS in some regions), we should follow the order of operations step by step:

1. First, simplify the expression inside the innermost brackets:

2. Now substitute the simplified expression back into the original expression:

3. Next, multiply the numbers inside the brackets:

4. Now substitute the new result back into the expression:

5. Finally, multiply the remaining numbers:

Therefore, the result of the expression 1.3 × [3.6 × {7.5 - 3.5 - 5.5}] is 18.72.
