If E = {even integers}, then insert the appropriate symbol `in` or `cancel(in)` in the blanks :
-8 . . . . . .E

Answer

To solve the problem, we need to determine whether -8 is an element of the set E, which consists of all even integers.

### Step-by-Step Solution:

1. **Identify the Set E**:
- The set E is defined as the set of all even integers. Even integers are numbers that can be divided by 2 without leaving a remainder. Examples of even integers include -4, -2, 0, 2, 4, etc.

2. **Determine if -8 is Even**:
- We need to check if -8 is an even integer. An integer is considered even if it can be expressed in the form of 2n, where n is an integer.
- In this case, -8 can be expressed as 2 × (-4), which shows that -8 is indeed an even integer.

3. **Conclusion**:
- Since -8 is an even integer, we can conclude that -8 belongs to the set E.
- Therefore, we insert the symbol `in` in the blank.

### Final Answer:
-8 **in** E
