    Transpositions are of order 2 then square of (ab) is identity. first two are easily done now. for last see the image of element in first cycle then in the second. for example image of a is b in first cycle and image of b is a in second so finally image of a is a. similarly image of b is c and image of c is b in second cycle so image of b is b similarly image of c is c , again it's identity.
