Question

answer!!! it please​

Answer 1

6.

ii)   a = 0 , b=-7/18 ,c = 4/3

   a)  a*b = b*a

      LHS:

      a*b= 0

      RHS:

      b*a= 0

         Hence Proved

     b) a(b.c) = (a.b)c = 0 , because any number multiplied by 0 is 0.

     c)  a(b+c) = a*b+a*c, because any number multiplied by 0 is 0 and 0+0 is also 0.

     d)  a(b-c) = a*b - a*c ,  because any number multiplied by 0 is 0 and 0-0 is also 0.
