Solution:
To make an 8-line-to-256 line decoder, we need to use a combination of smaller decoders.
We know that a 4-line-to-16-line decoder can decode 4 input lines into 16 output lines.
To make an 8-line-to-256-line decoder, we need to use 4 decoders in the following manner:
1. Connect the 3 most significant bits of the 8 input lines to a 4-line-to-16-line decoder. This will give us 16 output lines.
2. Connect the remaining 5 least significant bits of the 8 input lines to a 3-line-to-8-line decoder. This will give us 8 output lines.
3. Connect the 16 output lines from the first decoder to the enable inputs of 16 4-line-to-16-line decoders.
4. Connect the 8 output lines from the second decoder to the enable inputs of 8 4-line-to-16-line decoders.
5. Finally, connect the 256 output lines from the 17 decoders to the output lines of the 8-line-to-256-line decoder.
Therefore, the number of 4-line-to-16-line decoders required to make an 8-line-to-256-line decoder is 17.

5. Finally, connect the 256 output lines from the 17 decoders to the output lines of the 8-line-to-256-line decoder.
Therefore, the number of 4-line-to-16-line decoders required to make an 8-line-to-256-line decoder is 17.
