Question

Resolva:
Raiz quadrada de 8 - raiz quadrada de 18+ 2 raiz quadrada de 2 é igual:

Answer 1

$\sqrt{8} - \sqrt{18} + 2 \sqrt{2}$
$\sqrt{2*4} - \sqrt{2*9} + 2 \sqrt{2}$
$( \sqrt{2} * \sqrt{4} ) - (\sqrt{2} * \sqrt{9}) + 2 \sqrt{2}$
$( \sqrt{2} *2) - ( \sqrt{2} *3) + 2 \sqrt{2}$
$2 \sqrt{2} - 3 \sqrt{2} + 2 \sqrt{2}$
$(2 - 3 + 2) \sqrt{2}$
$\sqrt{2}$

Answer 2

$\sqrt{8} - \sqrt{18+2} + \sqrt{2}$
$\sqrt{2*2*2}- \sqrt{2*3*3}+ \sqrt{2}$
$\sqrt{2* 2^{2} }- \sqrt{2* 3^{2} }+ \sqrt{2}$
$2 \sqrt{2}-3 \sqrt{2}+ \sqrt{2}$
$1 \sqrt{2}$
