Answer:

This is a mathematical expression that involves exponents, parentheses, and subtraction. To simplify this expression, we need to follow the order of operations, which is:

Parentheses: Evaluate the expression inside the parentheses first.

Exponents: Evaluate the expression with exponents next.

Subtraction: Evaluate the expression with subtraction last.

Using this order, we can simplify the expression as follows:

12²-(9-7)³+6 = 12²-(2)³+6 = 12²-8+6 = 144-8+6 = 142

The expression 12²-(9-7)³+6 is equal to 142. Therefore, the missing value in the parentheses is 2. The expression can be rewritten as:

12²-(2)³+6 = 12²-(?)³+6
