18(x+y)的8次方(x-y)的六次方÷[3(x+y)的3次方(x-y)的3次方]²

18(x+y)的8次方(x-y)的六次方÷[3(x+y)的3次方(x-y)的3次方]²
18(x+y)的8次方(x-y)的六次方÷[3(x+y)的3次方(x-y)的3次方]²

18(x+y)的8次方(x-y)的六次方÷[3(x+y)的3次方(x-y)的3次方]²
18(x+y)的8次方(x-y)的六次方÷[3(x+y)的3次方(x-y)的3次方]²
=18(x+y)的8次方(x-y)的六次方÷9(x+y)的6次方(x-y)的6次方
=2(x+y)的2次方

=(18/9)(x+y)^(8-3*2)*(x-y)^(6-3*2)
=2(x+y)^2

18(x+y)^8(x-y)^6÷[3(x+y)^3(x-y)^3]^2
=18(x+y)^8(x-y)^6÷9(x+y)^6(x-y)^6
=2(x+y)^2

18(x+y)^8(x-y)^6÷[3(x+y)^3(x-y)^3]²
=18(x+y)^2[(x+y)(x-y)]^6÷9[(x+y)(x-y)]^6
=2(x+y)^2
