1) 218 : (27)2 = 218 : 214 = 218-14 = 24 = 16
2) (78)2 : (73)5 = 716 : 715 = 716-15 = 71 = 7
3) 115 · (113)7 : 1126 = 115 · 1121 : 1126 = 115+21 : 1126 = 1126 : 1126 = 1126-26 = 110 = 1
4) 92 · 27 = (32)2 · 33 = 34 · 33 = 34+3 = 37 = 2187
5) $$\frac{6^{12} \cdot (6^3)^5}{(6^5)^4 \cdot 6^4} = \frac{6^{12} \cdot 6^{15}}{6^{20} \cdot 6^4} = \frac{6^{12+15}}{6^{20+4}} = \frac{6^{27}}{6^{24}} = 6^{27-24} = 6^3 = 216$$
6) $$\frac{25^4 \cdot 125^{10}}{5^{37}} = \frac{(5^2)^4 \cdot (5^3)^{10}}{5^{37}} = \frac{5^8 \cdot 5^{30}}{5^{37}} = \frac{5^{8+30}}{5^{37}} = \frac{5^{38}}{5^{37}} = 5^{38-37} = 5^1 = 5$$
Ответ: 1) 16; 2) 7; 3) 1; 4) 2187; 5) 216; 6) 5.
