1.(2*10^3)*(10*10^5)^2/(5*10)
2.-8x^2y*(a-b)*1/2xy^2*(1/2b-1/2^a)^2

1.(2*10^3)*(10*10^5)^2/(5*10)2.-8x^2y*(a-b)*1/2xy^2*(1/2b-1/2^a)^2
乖乖,自己做.

(2*10^3)*(10*10^5)^2/(5*10)
=(2*1000)*(10*100000)^2/50
=2000*1000000^2/50
=2000*1000000000000/50
=2000000000000000/50
=40000000000000
(无语ing......)
-8x^2y*(a-b)*1/2xy^2*(1/2b-1/2^a)^2
(这是什么题?)
