find the 1s complement of binary number `(00101)_2` ?

Answer

To find the 1's complement of the binary number \( (00101)_2 \), we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of 1's Complement**:
The 1's complement of a binary number is obtained by flipping all the bits in the number. This means that every 0 becomes a 1, and every 1 becomes a 0.

2. **Write Down the Given Binary Number**:
The binary number we need to find the 1's complement for is \( 00101 \).

3. **Flip Each Bit**:
- The first bit is 0, which becomes 1.
- The second bit is 0, which becomes 1.
- The third bit is 1, which becomes 0.
- The fourth bit is 0, which becomes 1.
- The fifth bit is 1, which becomes 0.

4. **Combine the Flipped Bits**:
After flipping all the bits, we get:
- First bit: 1
- Second bit: 1
- Third bit: 0
- Fourth bit: 1
- Fifth bit: 0

Therefore, the 1's complement of \( 00101 \) is \( 11010 \).

### Final Answer:
The 1's complement of the binary number \( (00101)_2 \) is \( (11010)_2 \).
