If the expression is 4%2F%28sqrt%285%29%2Bsqrt%283%29%29 then 4%2F%28sqrt%285%29%2Bsqrt%283%29%29+=+2%2A%28sqrt%285%29-sqrt%283%29%29 and you're correct. Good job.


You can simplify the expression by distributing to get 2%2Asqrt%285%29-2%2Asqrt%283%29, but that's trivial.


Note: Using a calculator, we can find that





and





So this shows us that
