I am still relatively new to Matlab. I am trying to solve an equation, and when I try to run the code, it doesn't produce an answer.
syms x
eqn = sqrt(((((26892/(x)^3)+(254.7/(x^2)))/2)^2)+(6111.5/((x)^3))^2) == 19000;
sol = solve(eqn, x);
What am I doing wrong?

syms x
eqn = sqrt(((((26892/(x)^3)+(254.7/(x^2)))/2)^2)+(6111.5/((x)^3))^2) == 19000;
expand(eqn)
ans = 
solve is telling it can't find closed form expressions for the eqn
sol = solve(eqn, x)
sol = 
So it returns a solution as the roots of a polynomial. The values of these roots can be optained as follows
vpa(sol)
ans = 
Check
subs(eqn,ans)
ans =
