Question

raiz qaudrada de 8 menos raiz quadrada de 18 + 2raiz de 2 é igual a:
​

Answer 1

Resposta:

/8−18+22

\sqrt{2*4} - \sqrt{2*9} + 2 \sqrt{2}2∗4−2∗9+22

( \sqrt{2} * \sqrt{4} ) - (\sqrt{2} * \sqrt{9}) + 2 \sqrt{2}(2∗4)−(2∗9)+22

( \sqrt{2} *2) - ( \sqrt{2} *3) + 2 \sqrt{2}(2∗2)−(2∗3)+22

2 \sqrt{2} - 3 \sqrt{2} + 2 \sqrt{2}22−32+22

(2 - 3 + 2) \sqrt{2}(2−3+2)2

\sqrt{2}2
