First of all your question is wrong:
You say:
How can I export the entire pdf to powerpoint
But i think you want to say:
How can I import the entire pdf to powerpoint
So you can do it as:
1. Open your PDF in Reader.
2.If you have Reader 5 or earlier
a. Choose the Graphics Select Tool from the toolbar (click and hold the toolbar button to the right of the zoom tool; when the flyout menu appears, click the rightmost button on it).
b.Use the Graphics Select Tool to drag a rectangle surrounding the area of the page you'd like to use in your PowerPoint presentation.
c. Choose Edit, Copy or press Ctrl+C, then switch to PowerPoint and choose Edit, Paste or press Ctrl+V to paste a copy of the selected area of the PDF file into your presentation.
d. If the result is too low-rez, switch back to Reader and without changing anything else, type a higher zoom percentage into the zoom text box at the lower left of the Reader window, then re-do the copy and paste into PowerPoint.
3. If you have Reader 6
a. Use the snapshot tool (a camera icon with a dotted line around it on the Basic toolbar), drag the crosshairs to draw a box around area you want to copy. The snapshot tool automatically copies the selected area to the clipboard; you can then paste it into PowerPoint. If you want higher resolution, zoom in on the image while it's still selected, then rightclick it and choose "Copy Selected Graphic"
