1.解:(1)原式=36×(1/6)^2=36×1/36=1.
(2)原式=0.
(3)原式=4×9+6=42.
(4)原式=(- 3/4)×(-8)+(- 3/4)×2/3-(- 3/4)×1/3=6-1/2 + 1/4 = 23/4.
(5)原式= (-8)-13×(-2)=-8+26=18.
(6)原式=0-8÷(-64)-1/8=0+(8×1/64)- 1/8 = 1/8 - 1/8 = 0.
(7)原式=(-8)×0.5-2.56÷4=-4-0.64=-4.64
(8)原式=(-3/2)×(4/9-2)=(-3/2)×(-14/9)=7/3.
(9)原式=(9-25)÷(-2)=-16÷(-2)=8.
(10)原式=16÷(-8)-1/2=-1/2=-5/2.
