若x^n=3,x^m=2,则x^m+n=______,x^2m=3n=______?
若x^n=3,x^m=2,则x^m+n=______,x^2m=3n=______?
若x^n=3,x^m=2,则x^m+n=______,x^2m=3n=______?
x^(m+n)
=x^m×x^n
=2×3
=6
x^(2m+3n)
=x^(2m)×x^(3n)
=(x^m)²×(x^n)³
=2²×3³
=4×27
=108
x^(2m+3n)=x^m*x^m*x^n*x^n*x^n=2*2*3*3*3=108
x^m+n=x^n X x^m=3x2=6
x^2m+3n=(x^m)^2 X (x^n)^3=2^2X3^3=108
若x^m=6,x^n=9,则(2x^3m*x^2n) / (x^m*x^n)^2*x^n
若多项式x²-4x+3=(x+m)(x+n),则m+n=
若(x-4)(x-m)=x^2-x+n则n,m=
设集合M={x|x=2n+1,n∈N},N={x|x=3n,n∈N},则M∩N=
若（2x＋3）（x+m)=2x+5x-n,则m=?n=?若（2x＋3）（x+m)=2x+5x-n,则m=?n=?
已知x^2+2x-3=(x+m)^2+n,则m= ,n=
若(x+m)(x-5)=x^2-2x+3n,则m-n=正确结果是8,
对于集合M,N,定义M-N={x|x属于M且X不属于N},定义M*N=(M-N)∪(N-M)对于集合M,N,定义M-N={x|x属于M且X不属于N},定义M*N=(M-N)∪(N-M),集合A y=x^2-3X,x是实数,集合A y=2x,x是正实数,则A*B=
解方程[(m+x)/n]+3=(x-n)/m
若(x+3)(x+n)=x^2+mx-15,则m=?n=?guocheng
若x-7x-15=（x+m)(x+n),则m+n=
多项式x^2-4x+3=(x+m)(x+n),m=?n=?
(x-m)(x-1)=x²-3x+n,则m+n的值为?
(x+m)(x+2)=x的平方-6X+n,则m,n各是多少
(x+m)(x+n)=x^2-7x+mn,则 m+n的值为?
(2x-3)(x-n)=2x^2+5x+m求m与n
x^m×(x^n)^3÷[x^(m-1)×2x^(n-1)]=
若x^n=3,x^m=2,则x^m+n=______,x^2m=3n=______?
