Final answer:
The statement is true. The ideal op-amp assumption allows us to simplify the analysis of op-amp circuits and solve for the output voltage in terms of the input voltages and resistor values.
Step-by-step explanation:
The statement in question is true. When using the ideal op-amp assumption to solve for the output voltage, we assume that the op-amp has infinite open-loop gain, infinite input impedance, zero output impedance, and no input offset voltage or bias current. These assumptions allow us to simplify the analysis of op-amp circuits by assuming that the voltage at the inverting and non-inverting inputs are equal, and that no current flows into the inputs. Using these assumptions, we can apply the voltage divider rule and other circuit analysis techniques to determine the output voltage in terms of the input voltages and resistor values.
