Good day everyone. I need to calculate series of the function given above. But I can not find result. It writes "Error, (in series/function) improper op or subscript selector". How can I fix this error? Please help me.

Ek4:=sqrt((Ea^2*Eb^2-Eab^2*X5^2)*Ds);

((((1/2)*k((1/2)*k^2/m2+X2)^2/m1((1/2)*k^2/m2+X2)+X1((1/2)*k^2/m2+X2))*((1/2)*k((1/2)*k^2/m2+X1)^2/m2((1/2)*k^2/m2+X1)+X2((1/2)*k^2/m2+X1))-((1/2)*k((1/2)*k^2/m2+X1)^2/m1((1/2)*k^2/m2+X1)+X2((1/2)*k^2/m2+X1))*X5^2)*(((1/2)*k((1/2)*k^2/m2+X2)^2/m1((1/2)*k^2/m2+X2)+X1((1/2)*k^2/m2+X2)-(1/2)*k((1/2)*k^2/m2+X1)^2/m2((1/2)*k^2/m2+X1)-X2((1/2)*k^2/m2+X1))^2+4*((1/2)*k((1/2)*k^2/m2+X1)^2/m1((1/2)*k^2/m2+X1)+X2((1/2)*k^2/m2+X1))^(1/2)*X5^2))^(1/2)
