Question

Determine o valor das raízes (e/f) e Calcule (a/b/c)

Answer 1

a)
$\frac{\sqrt{2^2 . 2}}{2}$

$2 . \sqrt{2}$ 
            2  
$\sqrt{2}$        

b) $\frac{\sqrt{3^2 . 3} }{3}$
$3.\sqrt{ 3}$ = $\sqrt{ 3}$
            3
c) $\frac{\sqrt{ 2 . 3^2} }{\sqrt{ 2^2 . 3}}$
  $3.\sqrt{ 2}$               
  $2.\sqrt{ 3}$

e)$\frac{2.\sqrt{ 6^2}}{3}$
2 . 6  =  12  = 4
  3          3
f)$\frac{- 9.\sqrt{ 2^4 . 7}}{2}$
- 9 . $2^2 . \sqrt{ 7}$
                   2
$36 .\sqrt{ 7}$  = -18$\sqrt{ 7}$
               2
