I have no idea what this question is asking me:

27. Show that $\displaystyle y = Me^{ae^{kt}}$ is a solution for any constant a.

it gives me this hint:

dy/dt = ky ln(y/m).

I would assume that because it is an exponent that any constant for a would give a definable solution.

I do not know what it is I am trying to prove or what is going on, any help would be appreciated.

Thanks.
