edit: See swawips post. it is more instructive
Your aim is to kill white. You succeed if your three stone string survives. It has 3 liberties. W strings have more liberties except the lower one. That one has also 3 liberties. So your only chance is to attack these. But first you threaten to escape: D13. W has to block at E13 otherwise you indeed escape to safety. This exchange favours you. Next you can play D10 followed by D9. Now W cannot atari you because your stone at D13. W dies.
edit: I guess the problem is far too difficult for a novice. Even my solution will be difficult to you. There are many sites with easier problems for example gogameguru

The three surrounded black stones have only three liberties, while the white border group has four. The other white group seems to have even more (however it is not yet fully connected). Thus - from the liberty count - it seems that black is lost here. However, there is a move which (effectively) increases black's liberties and at the same time forces white to reply in a way, which does not decrease black's liberties again. ;-)
