Question

verify that (x÷y)-1 = x-1÷ y-1 by taking x=-5/11, y=7/3​...

Answer 1

Given: (x÷y)-1 = x-1÷ y-1 and x=-5/11, y=7/3​.

To find: Verify by using the value of x and y.

Solution:

• Lets consider LHS first, we have: (x÷y)-1

• Now by putting values of x and y in this, we get:

       (x / y) - 1 = ( -5/11 / 7/3​ ) - 1

                     = (-15 / 77 ) - 1

                     = -15 - 77 / 77

       LHS       = -92 / 77

• Lets consider RHS now, we have: x-1÷ y-1

• Now by putting values of x and y in this, we get:

         x-1 / y-1 = ( -5/11 - 1 ) / ( 7/3 - 1 )

                      = ( -16/11 ) / ( 4 / 3 )

        RHS       = (-12 / 11)

        So LHS ≠ RHS.

Answer:

        So from above we have verified that (x÷y)-1 ≠ x-1÷ y-1
