Please show all the steps.

1. Convert 1921 to its 32-bit binary representation. Express your answer in hexadecimal.

2. Convert 400 to base 7.

3. Convert -4016 to its Two's complement, 32-bit binary representation. Express your answer in hexadecimal.

4. What decimal number is represented 0x0000002B? (Recall 0x indicates the number is in hexadecimal.)

5. We want to add 0x80000000 and 0xA0000000. Assuming we're storing the result as a 32-bit, binary value, will this cause an overow?
