Question

Simplifique os radicais e efetue as operações:

Answer 1

Resposta:

a)$\sqrt{2} +\sqrt{2^{2} 2^{2} 2}$ = $\sqrt{2} + 4\sqrt{2}$ = $5\sqrt{2}$

b)$\sqrt{3^3} + \sqrt{3}$ = $9\sqrt{3} + \sqrt{3} = 10\sqrt{3}$

c)$3\sqrt{5} + \sqrt{2^{2} . 5} = 3\sqrt{5} + 2\sqrt{ 5} = 5\sqrt{5}$

d)$2\sqrt{2} + \sqrt{2^2 . 2 } = 2\sqrt{2} +2 \sqrt{ 2 } = 4\sqrt{ 2 }$

e)$2\sqrt{7} + \sqrt{2^2 . 7} =2\sqrt{7} + 2\sqrt{7} = 4\sqrt{7}$

f)$2\sqrt{5^2 . 2 } + 6\sqrt{2} = 10 \sqrt{2} + 6 \sqrt{2} = 16\sqrt{2}$

g)$\sqrt{5^2 . 3 } - 2 \sqrt{2^2 . 3 } +\sqrt{3^2 . 3 } = 5\sqrt{3} - 4\sqrt{3} + 3\sqrt{3} = 4\sqrt{3}$

h)$\sqrt{2^2 . 3 } - 9\sqrt{3} + \sqrt{5^2 . 3 } = 2\sqrt{3} - 9\sqrt{3} + 5\sqrt{3} = -2\sqrt{3}$
