帮我解决分式~1.(a-b)^2/(b-a)^32.(6y^2*-3x)/2y^33.(4c^3/5ab^2)/(2ac^3)4.(8a^2b^2)/(3b/4a)5.(-3a/bc^2)^26.(3a/a-b)^27.把/a^-1b^-3化成只含有正整数指数的形式8.(2/1-a)+(2a/a-1)9.^2^3/(1/a^3b^2)^410./(1+2y/x-y)
帮我解决分式~
1.(a-b)^2/(b-a)^3
2.(6y^2*-3x)/2y^3
3.(4c^3/5ab^2)/(2ac^3)
4.(8a^2b^2)/(3b/4a)
5.(-3a/bc^2)^2
6.(3a/a-b)^2
7.把/a^-1b^-3
化成只含有正整数指数的形式
8.(2/1-a)+(2a/a-1)
9.^2^3/(1/a^3b^2)^4

帮我解决分式~1.(a-b)^2/(b-a)^32.(6y^2*-3x)/2y^33.(4c^3/5ab^2)/(2ac^3)4.(8a^2b^2)/(3b/4a)5.(-3a/bc^2)^26.(3a/a-b)^27.把/a^-1b^-3化成只含有正整数指数的形式8.(2/1-a)+(2a/a-1)9.^2^3/(1/a^3b^2)^410./(1+2y/x-y)
1.(a-b)^2/(b-a)^3 =1/(b-a)
2.(6y^2*-3x)/2y^3 =-9x/y
3.(4c^3/5ab^2)/(2ac^3) =2/5a^2b^2
4.(8a^2b^2)/(3b/4a) =32a^3b/3
5.(-3a/bc^2)^2 =9a^2/b^2c^4
6.(3a/a-b)^2=9a^2/(a-b)^2
7./a^-1b^-3 =a^2b^3/(c+d)^2
8.(2/1-a)+(2a/a-1) =(2a-2)/(a-1)=2
9.<-(a^2/b)>^2<-(b/2a)>^3/(1/a^3b^2)^4 =(-ab/8)/(1/a^12b^8)=-a^13b^9/8
10.<1+(2y^2/x^2-y^2)>/(1+2y/x-y)
=[(x^2+y^2)/(x^2-y^2)]/[(x+y)/(x-y)]
=(x^2+y^2)/(x+y)^2
