b) 4 * (-6) *(-2) - 3 * (-6) * (-3) = -24 * (-2) - (-18) * (-3) = 48 + 64 = 112
c) (-6) * (-2) * (-3) - 2 * (-3)^2 = -36 - 18 = - 54
d) -2 * (-6) * (-3) - 5 * (-6)^2 = -36 - 5 * 36 = -36 - 180 = -216
liczę na naj ;) mam nadzieję, że pomogłam :)
4*(-6)(-2) - 3*(-6)(-3) = 4*12 - 3*18 = 48 - 54 = -6
(-6)(-2)(-3) - 2(-3)^2 = -36 - 18 = - 54
(-2)(-6)(-3) - 5(-6)^2 = -36 - 180 = -216
