Question

Efetue as operações com raiz:
a) √36+2.√100=
b) √2048+2.√4=
c) √36+√25-√49=
d) √100-√225+3.√49=
e) 2.√1+√169+√0=

Answer 1

a)
             $\sqrt{36} +2. \sqrt{100} = 6+2.10 = 26$
b)
             $\sqrt{2048} +2. \sqrt{4} = \sqrt{2.1024} +2.2=32 \sqrt{2} +4$
c)
             $\sqrt{36}+ \sqrt{25} - \sqrt{49} =6+5-7=4$
d)
             $\sqrt{100}- \sqrt{225} +3\sqrt{49} =10+15+3.7=46$
e)
             $2 \sqrt{1} + \sqrt{169} + \sqrt{0} =2.1+13+0=15$
