已知（-1/3xyz）²*M={1/3x^(2n+2)y(n+3)z^4}/5x^(2n-1)y^(n+1)z且自然数x、z满足2^x*3^(x-1)=72
求M的值

已知（-1/3xyz）²*M={1/3x^(2n+2)y(n+3)z^4}/5x^(2n-1)y^(n+1)z且自然数x、z满足2^x*3^(x-1)=72求M的值
由（-1/3xyz）²*M={1/3x^(2n+2)y(n+3)z^4}/5x^(2n-1)y^(n+1)z化简得
M=3/5xz
2^x*3^(x-1)=2^x*3^x/3=72
2^x*3^x=216=（2*3）^x=6^x
x=3
题目没给z的条件
M=9/5z
