已知x^m=3,x^n=2,计算x^2m+3n的值?已知x^m=3,x^n=2,计算x^2m+3n的值?已知x^m=3,x^n=2,计算x^2m+3n的值?x^(2m+3n)=(x^2m)×(x^3n
已知x^m=3,x^n=2,计算x^2m+3n的值?
已知x^m=3,x^n=2,计算x^2m+3n的值?
已知x^m=3,x^n=2,计算x^2m+3n的值?
x^(2m+3n)=(x^2m)×(x^3n)=[(x^m)^2]×[(x^n)^3]=(3^2)×(2^3)=9×8=72
x^(2m+3n)=x^2m乘以x^3n=x^m的平方乘以x^n的三次方等于3*3*2*2*2=72
x^2m+3n=x^2m*x^3n=3*3*2*2*2=72
x^2m+3n
=x^2m *x^3n
=(x^m)^2*(x^n)^3
=9x4
=36
