Question

数学题。。。帮帮忙啦~~~~~~~

已知x的m次方=2，x的n次方=3，求x的（3m+2n）次方的值

Answer 1

x^m=2,x^n=3

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

Answer 2

x的（3m+2n）次方=x^3m ×x^2n=2^3 × 3^2=72

Answer 3

x^m=2,x^n=3

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

Answer 4

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

Answer 5

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