To simplify the expression [( - 72) ÷ ( - 2) ] ^ { 2} - ( - 7) ⋅ ( - 11), follow these steps:

Step 1: Simplify the division inside the parentheses: (-72 ÷ -2) = 36. Step 2: Square the result: 36^2 = 1296. Step 3: Simplify the multiplication: (-7) ⋅ (-11) = 77. Step 4: Subtract the result of the multiplication from the result of the squared division: 1296 - 77 = 1219.

Therefore, the simplified expression is 1219.
