1:
5*8+6*8=40+48=88
(5+6)*8=88
2:
4*7+9*7=28+63=91
(4+9)*7=91
(5 + 6) * 8 = 11 * 8 = 88
(5 + 6) * 8 = 5 * 8 + 6 * 8 = 40 + 48 = 88
(4 + 9) * 7 = 13 * 7 = 91
(4 + 9) * 7 = 4 * 7 + 9 * 7 = 28 + 63 = 91
1)84 ; 2)60
Пошаговое объяснение:
1)(9+5)*6=84 6*(9+5)=84
2)(7+8)*4=60 4*(7+8)=60
(9 + 5) * 6 = 84
(9 + 5) * 6 = 14 * 6 = 84
(9 + 5) * 6 = 9 * 6 + 5 * 6 = 54 + 30 = 84
ответ: 84
(7 + 8) * 4 = 60
(7 + 8) * 4 = 15 * 4 = 60
(7 + 8) * 4 = 7 * 4 + 8 * 4 = 28 + 32 = 60
ответ: 60

1)84 ; 2)60
Пошаговое объяснение:
1)(9+5)*6=84 6*(9+5)=84
2)(7+8)*4=60 4*(7+8)=60
(9 + 5) * 6 = 84
(9 + 5) * 6 = 14 * 6 = 84
(9 + 5) * 6 = 9 * 6 + 5 * 6 = 54 + 30 = 84
ответ: 84
Выражение 2.(7 + 8) * 4 = 60
(7 + 8) * 4 = 15 * 4 = 60
(7 + 8) * 4 = 7 * 4 + 8 * 4 = 28 + 32 = 60
ответ: 60
