IGCSE Grade 6 Maths Finding missing operators
|
Solve the bracket first.
We have to solve the brackets first.
We can multiply to get the answer.
8,234 /41x5- 23 = 981.14
4.567/ 3 x 4 - 5 = 1.089
6,789x 13-11x5 = 441,230
The missing operators are division (/), square root (√), and exponentiation (^).
2 / √4 ^ √6 ^ 8 = 4
Solve the bracket first.
Make both sides equal.
o find the missing operators, we can work backward from the given result of 120.
Let's assign variables to the missing operators: 5 ?1 4 ?2 9 ?3 2 = 120
Starting from the right side, we have: 2 ?3 2 = 120
Since 2 ?3 2 equals 8, we rewrite the equation: 2 ? 8 = 120
Now, let's focus on the left side: 5 ?1 4 ?2 9 = 2 ? 8
To make 5 ?1 4 ?2 9 equal to 2 ? 8, we can deduce that the missing operators should be multiplication (x) and exponentiation (^) respectively. Thus, we rewrite the equation: 5 x 4 ^ 9 = 2 x 8
Evaluating the right side: 2 x 8 = 16
Now, evaluating the left side: 5 x 4 ^ 9 = 5 x 262144 = 1310720
Therefore, the missing operators that make the equation true are multiplication (x) and exponentiation (^).
