(1)(3m+4n)(3m-4n)(2)(2x+y)²-3x²
(1)(3m+4n)(3m-4n)
(2)(2x+y)²-3x²
(1)(3m+4n)(3m-4n)(2)(2x+y)²-3x²
(3m+4n)(3m-4n)=(3m)²-(4n)²=9m²-16n²
(2x+y)²-3x²=(2x+y)²-(√3y)²
=(2x+y+√3y)(2x+y-√3y)
=[2x+(√3+1)y]*[2x+(1-√3)y]
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)
(3m-4n)(4n+3m)-(2m-n)(2m+n)
4m(m-n)^2+4n(n-m)^3
[(m-n)^2*(m-n)^3]^2/(m-n)^4
[(m-n)^2*(m-n)^3]^2/(m-n)^4
(m-n)2(n-m)3(n-m)4化简
化简-3(m-n)²-(m-n)平方-3(m-n)+4m-n)的平方+2(m-n)-1
如果m除以n=17,m,n都是自然数,那么m和n的最小公倍数是() 1、m 2、n 3、17 4、m*n
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
(n-1)(n-2)(n-3)(n-4)……(n-m+1)(n-m)n大于m 的计算公式
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
[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),
(4(m-n)^3)/((n-m)^2)
1若m=n,则|m|=|n|;2若m=—n,则|m|=|n|;3若|m|=|n|,则m=—n;4若|m|=|n|,则m=n哪个对
