Hi-

In (1), letp = a + ib, whereaandbare real. Thenq = a - ib.Put these expressions in place of

pandqin the equation.

Expand the brackets, separate out the reals and imaginaries and put the real part equal to 3 and the imaginary part equal to 7.

This will give you a pair of simultaneous equations inaandb, which you can then solve.

In (2), letz = a + ib, whereaandbare real. Thenz* = a - ib.

Substitute these into the LHS, expand and then compare reals and imaginaries. Again, this gives two equations foraandb, which you can solve.

Is that enough to get you going?
