Answer 1

Răspuns:

a) 2⁸

2¹ = 2

2² = 4

2³ = 8

2⁴ = 16

_________

2⁵ = 32

8 : 4 = 2

U(2⁸) = 6

b) 3⁸

3¹ = 3

3² = 9

3³ = 27

3⁴ = 81

___________

3⁵ = 243

8 : 3 = 2 rest 2

U( 3⁸) = 9

c) 5⁸

U ( 5⁸) = 5

d) 5²⁰³ + 6²³⁵ + 8⁴²⁹ = 9

U ( 5²⁰³ ) = 5

U ( 6²³⁵) = 6

U ( 8⁴²⁹ ) = 8

8¹ = 8

8² = 64

8³ = 512

8⁴ = 4096

___________

8⁵ = 32768

429 : 4 = 107 rest 1

5 + 6 + 8 = 19

e) 2²⁰¹¹

2011 : 4 = 502 rest 3

U ( 2²⁰¹¹) = 8

f) 7²⁰¹¹

7¹ = 7

7² = 49

7³ = 343

7⁴ = 2401

______________

7⁵ = 16807

2011 : 4 = 502 rest 3

U (7²⁰¹¹) = 3

g) 3²⁰¹¹ + 4²⁰¹¹ = 1

3¹ = 3 4¹ = 4

3² = 9 4² = 16

3³ = 27

3⁴ = 81

2011 : 4 = 502 rest 3

U( 3²⁰¹¹) = 7

2011 : 2 = 1005 rest 1

U(4²⁰¹¹) = 4

7 + 4 = 11
