(-0,35) x 2 (-4) x (- trzy czwarte) x - oznacza razy . ;) ,proszę o pomoc będę wdzięczna 2,5 x (-2) trzy piąte x (-jedna trzecia) (-1) kwadratowe x (-0,9) (-0,1) x (-10) do potęgi 2 .

(-0,35)x2(-4)x(-3/4)=
(-0,7)(-4)x(-3/4)=
2,8x(-0.75)=2,1
(-0,35) *2 (-4) *(-3/4) = -0,7 *(-1) * (-3/1) = - 2,1
2,5 * (-2i3/5) * (-1/3) = 2 i1/2 *(-13/5)*(-1/3) = 5/2 * (-13/5)* (-1/3) = 65/30=
= 2 i5/30 = 2 i 1/6
(-1)^2 *(-0,9) = 1 * (-0,9) = - 0,9
(-0,1) *(-10)^2 = (-0,1) * 100 = - 10
