1.7n+[4m-7n-2(m-2n-3m)]-3m化简要过程谢谢
1.7n+[4m-7n-2(m-2n-3m)]-3m化简要过程谢谢
1.7n+[4m-7n-2(m-2n-3m)]-3m化简要过程谢谢
1.7n+[4m-7n-2(m-2n-3m)]-3m
=1.7n+[4m-7n-2m+4n+6m]-3m
=1.7n+(8m-3n)-3m
=1.7n-3n+8m-3m
=5m-1.3n
=1.7n+(4m-7n-2m+4n+6m)-3m
=5m-1.3n
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
4m(m-n)^2+4n(n-m)^3
(m-n)2(n-m)3(n-m)4化简
1/(m-n)-1/(m+n)-2n/(m^2+n^2)-4n^3/m^4+n^4)-8n^7/(m^8+n^8)-16n^15/(m^16+n^16)+32n^31/(n32-m32)
[(m+n)(m-n)-(m-n)²+2n(m-n)]÷4n
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)
[2(m+n)^5-3(m+n)^4+(-m-n)^3]÷[2(m+n)^3]
计算(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n)
(m+4n)(m-n)-6(m+2n)(m-3n),
1.7n+[4m-7n-2(m-2n-3m)]-3m化简要过程谢谢
2(m+n)2-(m+n)+4(m+n)-(m+n)2+3(m+n)2 化简求值
(m-n)(m^5+m^4n+m^3n^2+m²n^3+mn^4+n^5)
2(m+n)2²-(m+n)+4(m+n)-(m+n)²+3(m+n)² 计算
