求大神将一下表达式用matlab程序求解
其中赋值a=(10,20,30)
k=(-0.5,-1,-1.5)
m=(1.2,1.1,1.3)
n=(0.11,0.11,0.12)
求得到的x值,保留四位小数就可以了 拜谢

a=10;k=-0.5;m=1.2;n=0.11;
>> x=(a*k*m*n+sqrt(k^2*m^2*n^3+k^3*m^3*n^2-a^2*k*m*n^3))/(n^2+k*m*n)
x =
7.0725
>> a=20;k=-1;m=1.1;n=0.11;
>> x=(a*k*m*n+sqrt(k^2*m^2*n^3+k^3*m^3*n^2-a^2*k*m*n^3))/(n^2+k*m*n)
