show that the power absorbed by the load is half the power delivered by source when the load and source impedances are conjugates.

Please show what you've tried so far. If other people supply your homework answers, you won't end up learning much.

I have tried to use the formula of impedences,but still couldnot get it at all.

Maybe try with Z_Load = R + iX, and Z_Source as the conjugate of Z_Load?
What is the total impedance?
What is the total power across these resistances?
...Across each?

Answer the above guiding questions (in this forum), and it should help you understand the concept.

I got 2R as total impedance.After that what should I do?

Keep on answering the questions!
What is the total power across the impedances?
How much power is across each of the impedances?

And what does this tell you given what Z_source and Z_load are?

We are not going to do your homework for you. Please re-read the Rules link at the top of the thread. And then work on your homework/coursework problem and post your detailed work here.l

You have been given ample hints by the other posters. You should be able to solve this problem now on your own.
