化简4^n+2-2^2m+3/4^m-1
化简4^n+2-2^2m+3/4^m-1
[ 4^(n+2) - 2^(2m+3) ] / 4^(m-1)
= [ 2^(2n+4) - 2^(2m+3) ] / 2^(2m-2)
= 2^(2n-2m+6) - 2^5
= 4^(n-m+3) - 32

[(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
化简,1.[(m+n-p)(m+p+n)-(m+n)²]/(-p),2.[(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)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(3m-4n)(4n+3m)-(2m-n)(2m+n)

-5m(-m+3n)+4m(-4m-5/2n),其中m=2,n=-1
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),
