Question

Расставь знаки арифмитических действий и, если нужно, скобки так, чтобы получились верные равенства.   7  7  7  7 = 6                 7  7  7  7 = 8 7  7  7  7 = 15               7  7  7  7 = 294 

Answer 1

((7*7)-7):7=6

 

7+7:7+7=15

 

((7*7)+7):7=8

 

((7*7)-7)*7=294

 

Answer 2

(7 * 7 - 7) / 7 = 6                 (7*  7+  7)/  7 = 8

7  +7  / 7  +7 = 15               ((7*  7)-7) *7 = 294 

Answer 3

To solve this equation, let's break it down step by step: 7 + 7 + 7 + 7 = 6 First, let's simplify the left side of the equation: 7 + 7 = 14 14 + 7 = 21 21 + 7 = 28 So, the left side simplifies to 28. Now, let's compare it to the right side of the equation: 6 = 6 Since 28 is not equal to 6, the equation is not balanced. Therefore, there is no way to arrange the arithmetic operations and parentheses to make the equation true. Hence, the answer is that there is no solution to the given equation.
