Question

(√13+√17)2 solve this problem?
​

Answer 1

Answer:

The answer is $30+2\sqrt {221}$

Step-by-step explanation:

Using $(a+b)^2=a^2+b^2+2ab$

           $(\sqrt{13}+\sqrt{17})^2$

         $=(\sqrt{13})^2+(\sqrt{17})^2+2(\sqrt{13})(\sqrt{17})\\=13+17+2\sqrt{13\times 17}\\=30+2\sqrt {221}$
