4.oblicz

a) 23+(-17)=

b)(-46)+32=

c) 19-25=

d) (-34)+(-56)=

e) (-24)-35=

f) (-18)-(-24)=

g) (-2 i 1/3)*(-1 i 2/7)=

h) (-12 i 2/3):3 i 1/6

Answer 1

1. -1²=1
    3/5²=9/25
4.

a) 23+(-17)= 6

b)(-46)+32= -14

c) 19-25= -6

d) (-34)+(-56)= -90

e) (-24)-35= -59

f) (-18)-(-24)= 6

g) (-2 i 1/3)*(-1 i 2/7)= -3

h) (-12 i 2/3):3 i 1/6= -4

Answer 2

1.   -1i3/5 ^2= -8/5^2= 64/25

a) 23 +(-17)= 23 - 17 = 6

b) (-46) +32 = -14

c) 19 - 25 = - 6

d) (-34)+ (-56)= -34 -56 = -90

e) (-24) -35 = - 59

f) 9-18) -(-24)= -18 +24 = 6

g) (-2i1/3) *(-1i2/7) = (-7/3) * (-9/7)= (-1/1) * (-3/1) = 3/1 = 3

h) (-12i2/3) :3i1/6= -38/3 : 19/6 = -38/3 *6/19= -2/1 * 2/1 = -4/1= -4
