Question

efetue as adições e distrações de radicais

Answer 1

a)

$\boxed{\sqrt{36}+\sqrt{64}=6+8=14}$

b)

$\boxed{\sqrt{10}+\sqrt{10}=2\sqrt{10}}$

c)

$\boxed{5\sqrt{7}+3\sqrt{7}=8\sqrt{7}}$

d)

$\boxed{5\sqrt{2}-3\sqrt{2}+2\sqrt{2}=4\sqrt{2}}$

e)

$\boxed{\sqrt{9}-\sqrt{4}=3-2=1}$

f)

$\sqrt{50}=\sqrt{2.{5}^{2}}=5\sqrt{2}$

$\boxed{7\sqrt{2}+\sqrt{50}=7\sqrt{2}+5\sqrt{2}=12\sqrt{2}}$

g)

$3\sqrt{20}=3.2\sqrt{5}=6\sqrt{5}$

$\sqrt{32}=4\sqrt{2}$

$2\sqrt{45}=2.3\sqrt{5}=6\sqrt{5}$

$\sqrt{50}=5\sqrt{2}$

$3\sqrt{20}+\sqrt{32}-2\sqrt{45}+\sqrt{50}$

$\boxed{\boxed{6\sqrt{5}+4\sqrt{2}-6\sqrt{5}+5\sqrt{2}=9\sqrt{2}}}$
