Answer:

   1+i4\sqrt 3

Step-by-step explanation:

Formula used here is (a+b)^{2} =a^2+b^2+2ab

also, i^2=-1 and (\sqrt{x})^2=x

(2+i\sqrt{3})(2+i\sqrt{3})= (2+i\sqrt{3} )^{2}

                       = 2^{2} +(i\sqrt 3)^2+2\cdot2 \cdot i\sqrt3

                       =4+ (-3)+ i4\sqrt 3

                        =4-3+ i4\sqrt 3

                        =1+i4\sqrt 3
