2. (2/3) + (5/6) = (4/6) + (5/6) = (9/6) = (3/2) jadi 7 pangkat (3/2)
3. (3/2) + (-2/3) = (9/6) + (-4/6) = (5/6) jadi 2 pangkat (5/6)
4. (-3/4) + (-5/8) = (-6/8) + (-5/8) = (-11/8) jadi 4 pangkat (-11/8) atau 2 pangkat        (-11/4)
5. (-4/3) + (-3/4) = (-16/12) + (-9/12) = (-25/12) jadi 8 pangkat (-25/12) atau 2          pangkat (-25/4)
