Question

5) Simplifique os radicais e efetue as operações. a) √28 - 10√ 7
c) 6√3 + √75 =
d) 2√50 + 6√2 = b) 9√2+ 3√50 =​

Answer 1

Resposta:

a) 2 raiz de 7 - 10 raiz de 7 = - 8 raiz de 7

b) 9 raiz de 2 + 15 raiz de 2 = 24 raiz de 2

c) 6 raiz de 3 + 5 raiz de 3 =  11 raiz de 3

d) 10 raiz de 2 + 6 raiz de 2 = 16 raiz de 2

Answer 2

Resposta:

$a)\\ \sqrt{28} -10\sqrt{7} =\\ \\ \sqrt{2^2.7} -10\sqrt{7} =\\ \\ 2\sqrt{7} -10\sqrt{7} =\\ \\ \fbox{ -8\sqrt{7} }$

----------------------------

$b)\\ 9\sqrt{2} +3\sqrt{50} =\\ \\ 9\sqrt{2} +3\sqrt{2.5^2} =\\ \\ 9\sqrt{2} +3.5\sqrt{2} =\\ \\ 9\sqrt{2} +15\sqrt{2} =\\ \\ \fbox{ 24\sqrt{2} }$

----------------------------------------

$c)\\ 6\sqrt{3} +\sqrt{75} =\\ \\ 6\sqrt{3} +\sqrt{3.5^2} =\\ \\ 6\sqrt{3} +5\sqrt{3} =\\ \\ \fbox{ 11\sqrt{3} }$

-------------------------------

$d)\\ 2\sqrt{50} +6\sqrt{2} =\\ \\ 2\sqrt{2.5^2} +6\sqrt{2} =\\ \\ 2.5\sqrt{2} +6\sqrt{2} =\\ \\ 10\sqrt{2} +6\sqrt{2} =\\ \\\fbox{ 16\sqrt{2} }$
