  1. ~ Gửi cọu  (◍•ᴗ•◍)~
    B= 3:(-3/2)^2+1/9√36
    B= 3:9/4+2/3
    B= 3.4/9+2/3
    B= 12/9+2/3
    B= 4/3+2/3
    B= 6/3
    B=2
     

  2. B=3:(-3/2)^2+1/9.\sqrt{36}
    ->B=3:9/4+1/9.\sqrt{6^2}
    ->B=3 . 4/9+1/9.|6|
    ->B=3. 4/9+1/9. 6
    ->B=(3.4)/9+(1.6/9
    ->B=12/9+6/9
    ->B=(12+6)/9
    ->B=18/9
    ->B=2
