please help me in this fraction
add and solve
3b^3t^3/ 8d^2k^2 + 5y^2/ 2bk^3

There is no equation, so there is no "solving" to be done. Even if you had written an equation, it has too many variables to allow a solution.
The only common factor of the two terms is (1/2k^2). You could rewrite it as
[1/(2k^2)]*[3b^3t^3/(4d^2)+ 5y^2/(bk)]
