Răspuns:

Explicație pas cu pas:

a)

3,6→ -3,6

5/8→- 5/8

2,75→- 2,75

- 2³/₄→+2³/₄

1,6 →- 1,6

3²/₃→ - 3²/₃

1,3→ -1,3

b)

3,6=36⁽²/10⁽²=18/5=5/18

5/8=8/5

2,75=275⁽⁵/100⁽⁵=55⁽⁵/20⁽⁵=11/4=4/11

-2³/₄= (-2x4+3)/4= -11/4= - 4/11

1,6=16⁽²/10⁽²=8/5=5/8

3²/₃=(3x3+2)/3=11/3=3/11

1,3=13/10=10/13

-

c)

3,6=36/10=18/5

3²/₃=3/11

¹¹⁾18/5=198/55

⁵⁾3/11=15/11

198/55> 15/11

3,6> 3²/₃

-

d)

-⁴⁰⁾4/11+⁵⁵⁾5/8+⁴⁴⁾13/10

= -160/440+275/440+572/440

=115/140+572/440

= 687/440
