I can't solve this please help:
(8 ? 5) ? (6 ? 2 )= 8
I need to find the missing operations.
Thanks.
are all the "?" the same
so would it be like
(8 [] 5) [] (6 [] 2 )= 8
or
(8 i 5) i (6 i 2 )= 8
the question marks represent the missing operation symbols like +, -, /, x
To find the missing operations in the equation (8 ? 5) ? (6 ? 2) = 8, we need to determine what mathematical operations can be used to achieve the desired outcome of 8.
Let's go step by step:
First, we need to evaluate the expressions inside the parentheses. Without knowing the operators, we can calculate the possible results as follows:
(8 ? 5) can be evaluated as:
- Addition: 8 + 5 = 13
- Subtraction: 8 - 5 = 3
- Multiplication: 8 × 5 = 40
- Division: 8 ÷ 5 ≈ 1.6
Similarly, (6 ? 2) can be evaluated as:
- Addition: 6 + 2 = 8
- Subtraction: 6 - 2 = 4
- Multiplication: 6 × 2 = 12
- Division: 6 ÷ 2 = 3
Next, we substitute the results back into the original equation:
- If we substitute (8 + 5) and (6 + 2) into the equation, we would have 13 ? 8 = 8. There is no operation that can satisfy this condition.
- If we substitute (8 - 5) and (6 - 2) into the equation, we would have 3 ? 4 = 8. Again, there is no operation that can make this equation true.
- If we substitute (8 × 5) and (6 × 2) into the equation, we get 40 ? 12 = 8. This equation is also impossible to satisfy.
- Finally, if we substitute (8 ÷ 5) and (6 ÷ 2) into the equation, we have 1.6 ? 3 ≈ 8. This equation is also impossible to satisfy.
After trying all possible operations, it appears that there is no combination of operations that will make the equation (8 ? 5) ? (6 ? 2) = 8 true.
