Answer:
Explanation:
To make the expression equal to 79, you can place parentheses as follows:
(20 / (7 - 2 + (5^2 x 3)))
Let's break down the steps to understand how the expression is simplified:
1. Start with the original expression: 20 / 7 - 2 + 5^2 x 3.
2. Apply the exponentiation operation first: 5^2 = 25.
3. Perform the multiplication: 25 x 3 = 75.
4. Then, perform the division: 20 / 7 = 2.857.
5. Next, perform the addition and subtraction inside the parentheses: 2 - 2 = 0.
6. Finally, perform the remaining addition and subtraction: 0 + 75 = 75.
So, the expression (20 / (7 - 2 + (5^2 x 3))) simplifies to 75.
Please note that there might be other valid ways to place the parentheses in order to make the expression equal to 79. The given solution is just one of them.
