Answer 1

1) Вычислить
11100101011(2)[phone](2)=101010101000(2)
1000001(2)-11111(2)=100010(2)
1437(8)+7465(8)=11124(8)
70000(8)-6453(8)=61325(8)
ABCDF(16)+98765(16)=144444(16)
F000001C(16)-AABBFF(16)=EF55441D(16)
2) Перевести число111111101001010010100011100 из 2-ичной системы счисления в 8-ичную и 16-ичную системы счисления
111 111 101 001 010 010 100 011 100(2) = 775122434(8)
111 1111 0100 1010 0101 0001 1100(2) = 7F4A51C(16)

Answer 2

Calculation 1:

To calculate the given expressions, let's break them down step by step:

1) 111001010112 + 11011111012 = 10000012 - The binary numbers are added together to get the result. - The sum of 111001010112 and 11011111012 is 10000012.

2) 10000012 - 111112 = 14378 - The subtraction is performed between the decimal numbers. - The difference between 10000012 and 111112 is 14378.

3) 14378 + 74658 = 700008 - The addition is performed between the decimal numbers. - The sum of 14378 and 74658 is 700008.

4) 700008 - 64538 = 635470 - The subtraction is performed between the decimal numbers. - The difference between 700008 and 64538 is 635470.

5) ABCDF16 + 9876516 = F000001C16 - The hexadecimal numbers are added together to get the result. - The sum of ABCDF16 and 9876516 is F000001C16.

6) F000001C16 - AABBFF16 = 2 - The hexadecimal numbers are subtracted from each other. - The difference between F000001C16 and AABBFF16 is 2.

Calculation 2:

To convert the given binary number to octal and hexadecimal, let's follow these steps:

1) 1111111010010100101000111002 to octal - Group the binary number into sets of three digits from right to left: 111 111 101 001 010 010 100 011 100. - Convert each group of three binary digits to its octal equivalent: 7 7 5 2 2 4 2 3 4. - The octal representation of 1111111010010100101000111002 is 775224234.

2) 1111111010010100101000111002 to hexadecimal - Group the binary number into sets of four digits from right to left: 1111 1110 1001 0100 1010 0011 1000. - Convert each group of four binary digits to its hexadecimal equivalent: F E 9 4 A 3 8. - The hexadecimal representation of 1111111010010100101000111002 is FE94A38.

Therefore, the answers to the given calculations are: 1) 111001010112 + 11011111012 = 10000012 2) 10000012 - 111112 = 14378 3) 14378 + 74658 = 700008 4) 700008 - 64538 = 635470 5) ABCDF16 + 9876516 = F000001C16 6) F000001C16 - AABBFF16 = 2 7) 1111111010010100101000111002 to octal = 775224234 8) 1111111010010100101000111002 to hexadecimal = FE94A38
