To calculate the given expression: 5/9×[3+6/7]-[-3+5/7]×3/52, we can follow the order of operations (PEMDAS - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Step 1: Calculate the values inside the brackets first. - Inside the first bracket: 3+6/7 = 3.8571 (rounded to 4 decimal places) - Inside the second bracket: -3+5/7 = -2.2857 (rounded to 4 decimal places)

Step 2: Substitute the calculated values back into the expression. - 5/9×4 - (-2.2857)×3/52

Step 3: Perform the multiplication and subtraction. - 5/9×4 = 2.2222 (rounded to 4 decimal places) - (-2.2857)×3/52 = -0.165 (rounded to 3 decimal places)

Step 4: Subtract the second result from the first. - 2.2222 - (-0.165) = 2.3872 (rounded to 4 decimal places)

Therefore, the value of the expression 5/9×[3+6/7]-[-3+5/7]×3/52 is 2.3872.
