已知x^m=2,x^n=3,求x^3m+2n的值?
已知x^m=2,x^n=3,求x^3m+2n的值?

已知x^m=2,x^n=3,求x^3m+2n的值?
x^(3m+2n)
=x^3m*x^2n
=(x^m)^3*(x^n)^2
=2^3*3^2
=8*9
=72

x^3m+2n
=x^3m *x^2n
=(x^m)^3 *(x^n)^2
=2^3 *3^2
=8*9
=72

已知x^m=3,x^n=6 求 x^m-n,x^3m-2n的值已知x^m=1/3,x^n=2,求x^2m+3n 已知x^m=3,x^n=6,求x^(3m－2n) 已知x^m=2,x^n=5.(1)x^m+n、x^m-n的值；（2）求x^3m-2n的值已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N 已知单项式M、N满足2x(M+3x)=6x^2y^2+N,求M、N. 已知,单项式M,N满足2x（M+3x)=6x²y²+N,求M,N 已知单项式M N满足3x(M-5x)=6x^2y^2 求M N 已知m=3x^2+2x-1,n=-x^2-2+3x,求m-2n 已知:M=3x²+2x-1,N=-x²-2+3x,求M-2N 已知x^m=9,x^n=6,x^k=2,求x^m+2n+3k 已知x^m=9,x^n=6,x^k=2,求x^m+2n+3k 已知x^m=2,x^n=5,求x^3m+x^2n的值? 已知x^2-4x+3=(x-1)^2+m(x-1)+n,求m、n的值已知x^(m+n) =57,x^m =19,求x^3n的值已知x^(m+n) =57,x^m =19,求x^3n的值已知单项式M、N满足（6x^2y^3-M）/n=-2x+3,求M、N 已知单项式M、N满足3x(M+6x^2)=18xy+N,求M和N?
