[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5

[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5

[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5]
=[4a^2b^2*0.5a^3b^2c]^3/[-8a*a^(2*5)*b^5]
=[(4*0.5)*a^(2+3)*b^(2+2)c]/[-8*a^(1+10)*b^5]
=[2*a^5b^4c]^3/[-8*a^11*b^5]
=[2^3*a^(5*3)*b^(4*3)*c^3]/[-8*a^11*b^5]
=[8*a^15*b^12*c^3]/[-8*a^11*b^5]
=(8÷-8)*a^(15-11)*b^(12-5)*c^3
=-a^4b^7c^3

看错了

[(-2ab)^2*(0.5a^3b^2c)]^3/[-8a(a^2b)^5
=[4a²b²*0.5a³b²c]³/(-8)a^11b^5
=[2a^5b^4c]³/(-8)a^11b^5
=8a^15b^12c^3/(-8)a^11b^5
=-a^4b^7c^3
