Question

By taking x=-1/3, y=-3/5, z=-4/9, verify the following:

Answer 1

Answer:

15/4 not equal to the -4/3

Step-by-step explanation:

formula used

(a/b)^-1 = b/a

Answer 2

Answer:

x=-13     y=3/5       z=4/9

LHS =(-13 - 3/5) raised to -1

      =   -10/5

      = -2

     

RHS = -13 -3/5

       = -13 - 15

         = -28

.: LHS is not equal to RHS
