  1. Lời giải chi tiết:
    3:((-3)/2)^2+1/9.\sqrt{36}
    =3:9/4+1/(9).6
    =4/3+2/3
    =6/3
    =2

  2. $\text{3 :  ($\dfrac{-3 }{2}$)² + $\dfrac{1}{9}$  . $\sqrt{36}$}$
    $\text{=3 : $\dfrac{9}{4}$ + $\dfrac{1}{9}$ . 6}$
    $\text{=$\dfrac{4}{3}$ + $\dfrac{2}{3}$}$
    $\text{=$\dfrac{6}{3}$ = 2}$
