(1)0.125²º¹º×8(2)(-2)²º¹º×(-0.5)²ºº9

(1)0.125²º¹º×8(2)(-2)²º¹º×(-0.5)²ºº9
(1)0.125²º¹º×8
(2)(-2)²º¹º×(-0.5)²ºº9

(1)0.125²º¹º×8(2)(-2)²º¹º×(-0.5)²ºº9
1.
0.125²º¹º×8
=0.125²ºº9×0.125×8
=0.125²ºº9
2.
(-2)²º¹º×(-0.5)²ºº9
= -2×(-2²ºº9)×(-0.5)²ºº9
= -2×(-2×(-0.5))²ºº9
= -2×(1)²ºº9
= -2

(1)0.125=1/8
∴ 原式=0.125²º¹9
(2)-0.5=-1/2
∴ 原式=-2
