Question 1079800: Describe and correct the error.
Simplify the expression.
3+Sqrt(3) (5+Sqrt(5))=15+Sqrt(15)=15+Sqrt(15)
5-Sqrt(5) (5+Sqrt(5))=25-5=20
This is a fraction expression.

(3 + sqrt{3})(5 + sqrt{5})

Use FOIL to expand.

15 + 3sqrt{5} + 5sqrt{3} + sqrt15}

15 + 5sqrt{3} + sqrt{30(2 + sqrt{3})}

Nothing else can be done here.
