Question

используя в каждом случае4 раза цифру 7знаки арефметических действий и если надо скобки составь 5 выражений со значениями 5 6 7 8

Answer 1

7-((7+7):7)=5(7*7-7):7=67-((7-7):7)=7(7+7*7):7=8(7+7):7+7=9 

Answer 2

Arithmetic Expressions with the Given Numbers

Sure, I can help with that! Here are five arithmetic expressions using the numbers 5, 6, 7, and 8, each used exactly four times along with the arithmetic operators:

1. Expression 1: - (5 + 7) * (8 - 6) = 24 - Explanation: First, add 5 and 7 to get 12, then subtract 6 from 8 to get 2, and finally, multiply 12 by 2 to get 24.

2. Expression 2: - 7 * 8 - 5 + 6 = 55 - Explanation: First, multiply 7 by 8 to get 56, then subtract 5 to get 51, and finally, add 6 to get 55.

3. Expression 3: - 8 - 6 + 7 * 5 = 39 - Explanation: First, subtract 6 from 8 to get 2, then multiply 7 by 5 to get 35, and finally, add 2 to 35 to get 37.

4. Expression 4: - 8 * 7 - 6 + 5 = 51 - Explanation: First, multiply 8 by 7 to get 56, then subtract 6 to get 50, and finally, add 5 to get 51.

5. Expression 5: - (8 + 5) * 7 - 6 = 69 - Explanation: First, add 8 and 5 to get 13, then multiply 13 by 7 to get 91, and finally, subtract 6 to get 85.

I hope these expressions meet your requirements! If you have any more questions or need further assistance, feel free to ask!
