Расставь скобки так чтобы получилось правильное уравнение7×8+4÷4+2=177×8+4÷4+2=23

Answer 1

(7×8+4)÷4+2=17
7×(8+4)÷4+2=23

Answer 2

To make the equation true, you need to add parentheses in the right places. Here's how you can do it:

(7×8) + (4÷4) + 2 = 23

Explanation:

• 7 times 8 equals 56.
• 4 divided by 4 equals 1.
• Now the equation becomes: 56 + 1 + 2 = 23
• And, 56 + 1 + 2 equals 59, not 23.

Since you want the equation to be true with a result of 23, it is not possible by only adding parentheses. The original equation "7×8 + 4÷4 + 2 = 23" is not mathematically valid.
