No, you would be not able to apply the Master theorem here. As you can use the Master theorem under specific criteria I.e. the recurrance equation has to be like, T(n) = aT(n/b) + f(n).
If this not the case it's not possible. Also the a and b does not have to be the functions as well.
If the recurrance relation contains the root operator then it is possible to apply the Master theorem.
Ex: T(n) = T(root(n)) + f(n)
