In the following question, they ask for the frequency at which the gain would be 1.41 V/V. The dc or low frequency closed loop gain is 2V/V (6 dB). Is the solution of the following question done correctly? I think it is wrong as they get the answer for frequency to be 5MHz, while 5Mhz is the closed loop 3db frequency of the amplifier. The frequency resulting in 1.41 V/V gain aught to be larger than that. Please tell me if their solution is correct or not and if it is not then what is the correct one? enter image description here

    \$\begingroup\$ The answer looks good for me (6dB - 3dB = 3dB = 1.41 V/V) \$\endgroup\$
