1) a x (b - c + a) x (a - c) = -3 x (2 -(-2) +(-3)) x ( -3 - (-2))
                                        = -3 x (1) x (-1)
                                        =  3

2) (1 - 1/6) = 5/6

     1/2(1 - 1/6) = 1/2(5/6)
                       = 5/12

     1 - 1/2(1 - 1/6) = 1 - 5/12
                             = 7/12

      1/3(1 - 1/2(1 - 1/6)) = 1/3 (7/12)
                                   =  7/36
      
       1 - 1/3(1 - 1/2(1 - 1/6)) = 1 - 7/36
                                        = 29/36

3) = [tex] a^{6} [/tex] [tex] a^{-2} [/tex] [tex] b^{6} [/tex] [tex] b^{-3} [/tex] [tex] c^{6} [/tex] [tex] c^{-4} [/tex]
    = [tex] a^{4} [/tex] [tex] b^{3} [/tex] [tex] c^{2} [/tex] 

4) -8√13 - 10√13 = -18√13

5) 1³ , 2³, 3² ,3³, 4³, 5³  yang dihilangkan 3² = 9
