1、[(m-n)^2*(n-m)^3]^2/(m-n)^4
=[(m-n)^4*(n-m)^6]/(m-n)^4
=(n-m)^6
2、[(-x^5)^2]^3/[(x^4)^2/(x^2)^3]
=（x^10）^3/[(x^8/x^6)
=x^30/x^2
=x^15

[(m-n)^2*(n-m)^3]^2/(m-n)^4=[(n-m)^2*(n-m)^3]^2/(m-n)^4=[(n-m)^5]^2/(m-n)^4=(n-m)^10/(m-n)^4=
(m-n)^10/(m-n)^4=(m-n)^6
[(-x^5)^2]^3/[(x^4)^2/(x^2)^3]=(x^10)^3/(x^8/x^6)=x^30/x^2=x^28

[(m-n)²(n-m)³]²/(m-n)^4
=-(n-m)^10/(m-n)^4
=(n-m)^6
[(-x^5)²]²/[(x^4)²/(x²)³]
=[(-x^5)²]²/[(x^4)...

全部展开

[(m-n)²(n-m)³]²/(m-n)^4
=-(n-m)^10/(m-n)^4
=(n-m)^6
[(-x^5)²]²/[(x^4)²/(x²)³]
=[(-x^5)²]²/[(x^4)²/(x²)³]
=x^30/[x^8/x^6]
=x^30/x^2
=x^15
同底数幂的除法不是相减而是相除
比如2²/2³=1/2
5²/5³=1/5
x*x / x*x*x = 1/x

指数的运算比幂运算低一级：即幂做乘方，指数做乘法；幂做乘除法，指数做加减法
