Please can you help me do the following. Where a k and B are positive constants

Please can you help me do the following. Where a k and B are positive constants

syms x a k B

solve(((2*a)/7)*x^(3.5)-2.5*a*k*x^(2.5)+B,x)

No clear question.

please can you solve for x

If a, k and B are constants just asign the value they have and solve, there is no need to declare them as a syms variable.

 >> syms x
  >> a=1; k=1; B=1;
  >> solve(((2*a)/7)*x^(3.5)-2.5*a*k*x^(2.5)+B,x)

Thank you. It gives some idea to solve my problem

[Carlos]

What are the values for the constants ? Do you need to solve the system for different values of your constants?
