Question

calcule o valor das expressões ( √18+ √98+ √200)÷(2√2+ √8)?

Answer 1

18 / 2 
  9 / 3
  3 / 3
  1
$\sqrt{2.3 ^{2} } = 3 \sqrt{2}$

98 / 2
49 / 7
  7 / 7
  1
$\sqrt{2.7 ^{2} } = 7\sqrt{2}$

200 / 2
100 / 2
  50 / 2
  25 / 5
    5 / 5
    1
$\sqrt{2.2 ^{2}.5 ^{2} } = 10 \sqrt{2}$

8 / 2
4 / 2
2 / 2
1
$\sqrt{2.2 ^{2} } = 2 \sqrt{2}$

(3√2 + 7√2 + 10√2) ÷ (2√2 + 2√2) = 
(20√2) ÷ (4√2) = 5
