Consider a scale-free network that has $N={10}^7$ nodes, each of them connected to at least one node, and with at least one leaf. If the degree exponent is $\gamma =2.5$, what is the maximum expected degree of this network? Round the result to the nearest integer.

1. $k_{max}=75$
2. $k_{max}=630$
3. $k_{max}=3162$
4. $k_{max}=46415$
5. None of the above.
