An op-amp with an open-loop gain of 6x105 and Vcc = 15 V has an output voltage of 3 Volts. If the inverting-input voltage is -1.8 microVolts then determine the non-inverting input voltage in microVolts to the single digit decimal place. Do not enter units. For example, if you calculate 3.1x10-6 Volts as your answer then enter 3.1. Similarly, if you calculate 1.872 x10-5 Volts as your answer then enter 18.7 (since this is 18.7 microvolts).
