1.Oblicz: 1) (-0,2) razy (-100)-4 i 1/2 razy 2/3 =....... 2) (-2,7 - 3 : 10) do potęgi 3 razy (-1)=......... 3) (-10) razy (1 i 1/5 -5,5)=............ 4) (-7) razy (-10 do potęgi 2) - (-70 = ..... same wyniki , z góry dzięki NA DZISIAJ !!

1) ( -0,2) * (-100) -4i1/2*2/3 = 20 -9/2 * 2/3 = 20 - 3/1 * 1/1= 20-3 = 17
2) (-2,7 -3 :10) do3*( -1) = (-2,7 -0,3)do3 *(-1)= -3 do3*(-1)= -27 * (-1)= 27
3) (-10)* (1i1/5-5,5) = (-10) * (1,2 -5,5) = (-10) * (-4,3) = 43
4) (-7)*(-10)do2 -(-70)= (-7)* 100 -(-70)= -700 + 70 = - 630
