1) 6(-2/3) (6(-2/3)-4) + 9(-1/3) (3-4(-1/3))= 6(-2/3)(-10/3) + 9(-1/3)(3+4/3)= -4(-10) - 3(3+4)= 40 - 21= 19Ответ: 19
2) 2(-4)(-4-0.5) - 0.5(3(-4)-0.5) - 0.5(0.5+6)= 2(-4)(-4.5) - 0.5(-12.5) - 0.5(6.5)= 2(18) + 6.25 - 3.25= 36 + 6.25 - 3.25= 39Ответ: 39
1) 6(-2/3) (6(-2/3)-4) + 9(-1/3) (3-4(-1/3))
= 6(-2/3)(-10/3) + 9(-1/3)(3+4/3)
= -4(-10) - 3(3+4)
= 40 - 21
= 19
Ответ: 19
2) 2(-4)(-4-0.5) - 0.5(3(-4)-0.5) - 0.5(0.5+6)
= 2(-4)(-4.5) - 0.5(-12.5) - 0.5(6.5)
= 2(18) + 6.25 - 3.25
= 36 + 6.25 - 3.25
= 39
Ответ: 39
