3 8 √1
(-----)²x----- + --------- (√1 = 1 e √144 = 12)
4 9 √144

3² 8 1

Temos que:

$(\dfrac{3}{4})^2\cdot\dfrac{8}{9} + \sqrt{\dfrac{1}{144}} =$
$\dfrac{3^2}{4^2} \cdot\dfrac{8}{9} + \sqrt{\dfrac{1}{144}} =$
$\dfrac{9}{16}\cdot\dfrac{8}{9} + \sqrt{\dfrac{1}{144}} =$
$\dfrac{9}{16}\cdot\dfrac{8}{9} + \sqrt{\dfrac{1^2}{12^2}} =$
$\dfrac{9}{16}\cdot\dfrac{8}{9} + \dfrac{1}{12} =$
$\dfrac{72}{144} + \dfrac{1}{12} =$
$\dfrac{1}{2} + \dfrac{1}{12} =$
$\dfrac{6}{12} + \dfrac{1}{12} =$
$\dfrac{6 + 1}{12} =$
$\dfrac{7}{12} =$
$0,58333...$

Espero ter ajudado.
