Question

Simplify of the following expression :-

`(3+sqrt3)(2+sqrt2)`

Solution

`(3+sqrt3)(2+sqrt2) = 3(2+sqrt2)+sqrt3(2+sqrt2)`
Left Distributive law of multiplication over addition

                            `= (3)(2)+3sqrt2+(sqrt3(2))+(sqrt3)(sqrt2)`

                            `= 6+3sqrt2+2sqrt3+sqrt((3)(2))`            `thereforesqrtasqrtb=sqrt(ab)`

                            `= 6+3sqrt2+2sqrt3+sqrt6`

  Is there an error in this question or solution?
