How would i turn this into a flat surface?

Look at this image and explain how i could smooth this out please.

You can use a relax command (W -> LoopTools -> Relax) from LoopTools add-on:

LoopTools included in blender, you can enable it in user preferenses.

Probably by selecting all verticies and then running the smooth command a number of times. You can access this a number of ways, but the easiest is via the "Specials Menu" (Press W)
