Question

问几道数学题，要过程，谢谢

化简：(1/2x^2y-2xy+y^2)乘3xy (y^2×y^3)÷(y×y^4) x^乘x^3+x^7÷x^2 m^5÷m^2×m a^4+(a^2)^4-(a^2)^2

Answer 1

分开乘，谢谢，步骤没法写镇氏铅御好
（1）3/核盯2x^3y^2-6x^2y^2+3xy^3
(2)y^5/y^5=1
(3)x^4+x^5
(4)m^3*m=m^4
(5)a^4+a^8-a^4+a^8

Answer 2

(1/2x^2y-2xy+y^2)乘3xy
=3/带拦者2x^3y^2-6x^2y^2+3xy^3

(y^2×y^3)÷(y×y^4)
=y^5/蠢薯衡罩y^5
=1

x^2乘x^3+x^7÷x^2
=x^5+x^5
=2x^5

m^5÷m^2×m
=m^3*m
=m^4

a^4+(a^2)^4-(a^2)^2
=a^4+a^8-a^4
=a^8
