how to solve this equation?

Hello

i have this equation:

x=((10/11)^5.5)*((1+0.1*m^2)^5.5)/m

I want to calculate the values of 'm' by putting values of 'x' from 1 to 60 with interval of .01 and then store all the values of m in a matrix array.

Are you absolutely certain you want to do this?

This code:

syms m x 
Eqn = x == ((10/11)^5.5)*((1+0.1*m^2)^5.5)/m;
[sm,parms,cndx] = solve(Eqn, m, 'ReturnConditions',true);

that because of the fractional exponent, produces a 22-degree polynomial:
