▼优质解答
答案和解析
(-2xy^2)^2(-0.5x^2y)^3(-2/3x^2y^3)
=4x^2y^4*(-1/8x^6y^3)*(-2/3x^2y^3)
=4*1/8*2/3*x^2y^4*x^6y^3*x^2y^3
=1/3*x^2x^6x^2*y^3*y^3y^4
=1/3*x^(2+6+2)y^(3+3+4)
=1/3x^10y^10
=4x^2y^4*(-1/8x^6y^3)*(-2/3x^2y^3)
=4*1/8*2/3*x^2y^4*x^6y^3*x^2y^3
=1/3*x^2x^6x^2*y^3*y^3y^4
=1/3*x^(2+6+2)y^(3+3+4)
=1/3x^10y^10
