You can put this solution on YOUR website!
%28sqrt%283%29+%2B+sqrt%282%29%29sqrt%285%29+=+sqrt%287%29

But that is a false equation! With a calculator you can easily 
discover for yourself that the left side of the equation, 

%28sqrt%283%29+%2B+sqrt%282%29%29sqrt%285%29 is approximately  7.035261006

whereas the right side of the equation, 

sqrt%287%29 is approximately 2.645751311
