Question

1. Najmniejsza liczba to :

A.-96 B.0 C. -101 D.-152

2.Liczby 51 i ( -51) są :

A . odwrotne B przeciwne C o tym samym znaku D równe

3. obicz

A) 25+(-53)= B) (-48) + (-39)=

(-42 + 61 = 53 - (-27)=

32 + (-32)= (-23) - (-41)=

C) 5 x (-13) = D) (-4) do podegi 3 =

(-12)x(-8)= (-63) / (-9)=

(-2) do potegi 4 = 52 / (-13)=

/= to znaczy dzielić x= mnożyć

Answer 1

1. D  -152

 

2. B przeciwne

 

3. a) 25 - 53 = -28

  -42 + 61 = 19

32 - 32 = 0

 

b)  -48 - 39 = - 87

   53 + 27 = 80

  -23 + 41 = 18

 

c) 5 · (-13) = -65

  (-12) · (-8) = 96

(-2)⁴ = 16

 

d) (-4)³ = - 64

(-63)/(-9) = 7

52/(-13) = -4

Answer 2

1.

D. -152

 

2.

B. przeciwne

 

3.

A) 25+(-53)= 25 - 53 = -28

   (-42 + 61 = -42 + 61 = 19

  32 + (-32)=32 - 32 = 0

 

B)  (-48) + (-39)= -48 - 39 = - 87                                 plus i minus zawsze daje minus

   53 - (-27)= 53 + 27 = 80                                            plus i plus zawsze daje plus

   (-23) - (-41)= -23 + 41 = 18                                      minus i minus zawsze daje plus

                                                                                          

C) 5 x (-13) = -65

  (-12) x (-8) = 96

(-2)⁴ = 16

 

D) (-4)³ = - 64

     (-63)/(-9) = 7

     52/(-13) = -4
