Answer:

 \frac{30}{5 \sqrt{3} - 3 \sqrt{5}  }    \times  \frac{5 \sqrt{3} + 3 \sqrt{5}  }{5 \sqrt{3} + 3 \sqrt{5}  }  \\  \frac{30(5 \sqrt{3}  + 3 \sqrt{5} )}{ {(5 \sqrt{3)} }^{2}  -   {(3 \sqrt{5)} }^{2}  }    \\ \frac{30(5 \sqrt{3} + 3 \sqrt{5})  }{75 - 45}  \\  \  \frac{30(5 \sqrt{3} + 3 \sqrt{5})  }{30}  \\  = 5 \sqrt{3}  + 3 \sqrt{5}
