Hi,

NSolve does not work at all with exponential,logs,and trigc or
hyperbolic functions. In order to solve these types of equations
numerically you should use FindRoot command.

FindRoot [{k*.01^p==10,k*.1^p==1},{k,-1},{p,0}]

I think that it is using some iterative method to find an approximate
value.

Regards,
