An NPN transistor operates as a common emitter amplifier, with a power gain of 60 dB. The input circuit resistance is $100 \Omega$ and the output load resistance is $10 \mathrm { k } \Omega$. The common emitter current gain $\beta$ is:
(1) $6 \times 10 ^ { 2 }$
(2) $10 ^ { 2 }$
(3) $10 ^ { 4 }$
(4) 60
