Question

(root 3+root10)square​

Answer 1

Answer:

$( \sqrt{3} + \sqrt{10} ) {}^{2} \\ ( \sqrt{3} ) {}^{2} + ( \sqrt{10} ) {}^{2} + 2( \sqrt{3} )( \sqrt{10} ) \\ 3 + 10 + 2 \sqrt{30} \\ 13 + 2 \sqrt{30}$

Answer 2

Answer:

$(\sqrt{3} +\sqrt{10} )^{2}$

Apply (a+b)^2 = a^2 + 2ab + b^2

So by solving further you get,

$13 + 2\sqrt{30}$
