Question 8

Multiply: 
A) 
B) 
C) 
D) 
E)

Accepted Answer

To multiply, we need to perform hexadecimal multiplication just like in decimal multiplication. The result of multiplying c and e is a8, and f and e is d8. We carry over the 1 to the next set of digits in the multiplication. Continuing the multiplication and carrying over, we get 203ba7a05dcbe6c03d6e5_tb8311_11. Therefore, the closest option is D, with the difference being only in the last digit of the hexadecimal result, which should be f instead of 8.

Question 16

Multiply: 
A) 
B) 
C) 
D) 
E)

Accepted Answer

In order to multiply two numbers in hexadecimal, we can use the same method as in regular multiplication, but using hexadecimal digits. We start with multiplying the last digit of the second number (B) by each digit of the first number (9, A, 8, 6, 9, B, 1, 1), and then we move to the second to last digit of the second number (9) and repeat the process but adding a zero to the right. We continue like this until we have multiplied all digits of the second number.

Doing this multiplication results in the following:

1 1 e b 6 9 d a
          9 e 9 8 e 8 9 a f 9 4 c 7 c 2 2 6 4 0 5 e 2 5
       -----------------------------------------------
      9 d 91 04 be 1 55 fa 33 a 6 d c 6 8 c 1 2 9 3 3 a a
     8 e 98 0b 7d 2a 2e 50 b0 d9 b7 1c e 6b f8 17 5b 7 f
    --------------------------------------------------
     7 e 2a 0f 72 1 81 8f 83 83 80 88 a 5 5b ef bc 1 2 9

Now, we need to add the "TB8311_11" at the end of the result, which gives us:

7e2a0f721818f8383808880a5efbc129TB8311_11

The corresponding choice is B.
