How can you calculate impedance using the formula Z = R + jX?

[chan1]

Homework Statement

know that the frequency is10hz and 4.7kΩ resistor calculating the impedance in kΩ
i spend half hour on this and still have no idea what to do ,tell me the formula or the step thanks

4.7K ohms.

what about when frequency is 100hz, 1khz 10khz? what's th impedance
thanks

4.7K ohms. Resistance is independent of frequency unless you were given a model of a non-ideal resistor.
