  The first one can be simplified to (r^2)t=5832, for integers this gives 16 different solutions, but as both numbers are positive, this is reduced to 8, and as r>t, there are only the following options: r=54 and t=2, or r=27 and t=8, therefore C is the correct answer.
  The second can be (a^3)(b^2)=432, this gives a=3 b=4, therefore B is the correct answer.
