internal amplifier stages

A certain op-amp has three internal amplifier stages with midrange gains of 30 dB, 40 dB, and

20 dB. Each stage also has a critical frequency associated with it as follows:

f c1 = 600 Hz, fc2 = 50 kHz, and f c3 = 200 kHz.

(a) What is the midrange open-loop gain of the op-amp, expressed in dB?

(b) What is the total phase shift through the amplifier, including inversion, when the signal frequency is 10 kHz?
