Question

Raciocialize o denominador de cada expressão:

Answer 1

Resposta:

a) $\sqrt{6}$

b) 3$\sqrt{3}$

c) $\frac{\sqrt{10} }{2}$

d) 2$\sqrt{5}$

e) $\frac{\sqrt{6} }{2}$

f) $\frac{\sqrt{7} }{7}$

Explicação passo-a-passo:

a) $\frac{6}{\sqrt{6} }$ . $\frac{\sqrt{6} }{\sqrt{6} }$ = $\frac{6\sqrt{6} }{6}$ = $\sqrt{6}$

b) $\frac{9}{\sqrt{3} }$ . $\frac{\sqrt{3} }{\sqrt{3} }$ = $\frac{9\sqrt{3} }{3}$ = 3$\sqrt{3}$

c)  $\frac{\sqrt{5} }{\sqrt{2} }$ . $\frac{\sqrt{2} }{\sqrt{2} }$ =$\frac{\sqrt{10} }{2}$

d) $\frac{20}{2\sqrt{5} }$ . $\frac{\sqrt{5} }{\sqrt{5} }$ = $\frac{40\sqrt{5} }{20}$ = 2$\sqrt{5}$

e) $\frac{3}{\sqrt{6} }$ . $\frac{\sqrt{6} }{\sqrt{6} }$ = $\frac{3\sqrt{6} }{6}$= $\frac{\sqrt{6} }{2}$

f) $\frac{1}{\sqrt{7} }$ . $\frac{\sqrt{7} }{\sqrt{7} }$ = $\frac{\sqrt{7} }{7}$
