4. Найдите коэффициент произведения и подчеркните его: a) 8c ⋅ 5 б) -3 ⋅ (-2a) в) -1,4 ⋅ 4х г) 9у ⋅ (-8) д) -0,1р ⋅ 7 e) -t ⋅ k ж) -f ⋅ (-b) з) 2,5 ⋅ 3a и) -18c ⋅ (-1,5) к) -4,2ab ⋅ 2 л) 1,8 ⋅ 7ху м) 7,3z ⋅ (-n)

Находим коэффициент произведения и подчёркиваем его:

• а) 8c ⋅ 5 = 40c
• б) -3 ⋅ (-2a) = 6a
• в) -1,4 ⋅ 4х = -5,6х
• г) 9у ⋅ (-8) = -72у
• д) -0,1р ⋅ 7 = -0,7р
• e) -t ⋅ k = -1tk
• ж) -f ⋅ (-b) = 1fb
• з) 2,5 ⋅ 3a = 7,5a
• и) -18c ⋅ (-1,5) = 27c
• к) -4,2ab ⋅ 2 = -8,4ab
• л) 1,8 ⋅ 7ху = 12,6ху
• м) 7,3z ⋅ (-n) = -7,3zn
