can apple mouse be bluetoothed with ipad air 2

No. The iPad is not programmed to have a cursor.

NO external Bluetooth mice work on Apple iDevices and iOS.

There is no physical pointer/cursor programmed into iOS for an external mouse or trackpad input device to navigate on screen.

Your fingers are your mouse input device.

iOS has an insertion point "I" beam cursor that can now controlled by invoking the iOS software keyboard and then do a two-finger single tap to turn the entire software keyboard area into a giant trackpad.

If you use a two-finger double tap within the keyboard area, you can highlight words, lines of text or entire paragraphs for editing.

Good Luck!
