Answer 1

1) a. 8592= 8 * 10^3 + 5* 10^2 + 9*10^1 + 2*10^0

b. 2703= 2*10^3 + 7* 10^2 + 3*10^0

c. 47021= 4*10^4 + 7*10^3 + 2*10^1 + 1*10^0

2. a) 2/2= 1 rest 0

1/2=0 rest 1

deci 2 va fi in baza 2 = 10

b) 3/2= 1 rest 1

1/2=0 =resr 1

3=11

c) 4/2=2 rest 0

2/2=1 rest 0

1/2=0 rest 1

4=100

d) 5/2=2 rest 1

2/2=1 r 0

1/2=0 r 1

5=101

e) 6/2=3 r 0

3/2=1 r 1

1/2=0 r 1

6=110

f) 7/2=3 r 1

3/2=1 r 1

1/2=0 r 1

7=111

g) 8/2=4 r 0

4/2=2 r0

2/2=1 r0

1/2= 0 r 1

8=1000

h) 9/2=4 r 1

4/2=2 r 0

2/2= 1 r 0

1/2 = 0 r 1

9=1001

i) 10/2=5 r 0

5/2= 2 r 1

2/2 = 1 rest 0

1/2= 0 rest 1

10=1010

j) 11/2= 5 r 1

5/2= 2 r 1

2/2 = 1 rest 0

1/2= 0 rest 1

11=1011

k) 12/2=6 r 0

6/2=3 r 0

3/2=1 r 1

1/2=0 r 1

12=1100

l) 13/2=6 r 1

6/2=3 r 0

3/2=1 r 1

1/2=0 r 1

13=1101
