Ответ:

1. 17 13/30

2. 29 29/30

Пошаговое объяснение:

1-ый

1) 8 13/30¹ + 13 4/5⁴ = 8 13/30 + 13 24/30 = 21 47/30 = 22 17/30

2) 22 17/30¹ - 5 5/6(доп.множитель 5) = 22 17/30 - 5 25/30 = 21 47/30 - 5 25/30 = 16 22/30

3) 16 22/30¹ + 7/10³ = 16 22/30 + 21/30 = 16 43/30 = 17 13/30

2-ой

1) 21 4/5(доп.множ.6) + 1 5/6(доп.множ.5) = 21 24/30 + 1 25/30 = 22 49/30 = 23 19/30

2) 22 29/30 - 9 7/30 = 13 22/30

3) 13 22/30⁴ + 16 7/24(доп.множ.5 = 13 88/120 + 16 28/120 = 29 116 /120 = 29 29/30
