In addition to the required readings in this unit, the Unit Study Guide covers many of the topics in this assignment.
1. Identify the decimal equivalents for the following (use the binary chart in the study guide):
|
2^0 |
= |
1 |
|
2^1 |
= |
|
|
2^2 |
= |
|
|
2^3 |
= |
|
|
2^4 |
= |
|
|
2^5 |
= |
|
|
2^6 |
= |
|
|
2^7 |
= |
|
|
2^8 |
= |
|
2. Manually convert the decimal numbers into binary numbers in the table below. You must show your work using the conversion process.
