Question

1) AF(16)+767(8) = ...(2); 2)1000011010(2) - 11011101(2)=... (2)

Answer 1

Ответ:

1) AF(16) ---> 10101111(2) (по таблицам тетрад)

  767(8) ---> 111110111(2) (по таблицам триад)

10101111 + 111110111 = 1010100110 (2)

2) 1000011010(2) - 11011101(2)= 100111101 (2)

Answer 2

1. To perform the addition AF(16) + 767(8) and convert the result to base 2, we need to convert the hexadecimal number AF to binary and the octal number 767 to binary first. Then we can add the two binary numbers and convert the result back to base 2.

AF(16) = 10101111(2) 767(8) = 111110111(2)

Now, let's add the two binary numbers:

10101111

• 111110111

---

100101010(2)

Therefore, AF(16) + 767(8) = 100101010(2).

2. To perform the subtraction 1000011010(2) - 11011101(2) and convert the result to base 2, we can directly subtract the two binary numbers.

1000011010

• 11011101

---

1010101(2)

Therefore, 1000011010(2) - 11011101(2) = 1010101(2).
