Question

verify that (x÷y)÷z is not equal to x÷(y÷z) by taking x=-1/3,y=3/5,z=-7/11​

Answer 1

Answer:

(-1/3 ÷ 3/5) ÷ -7/11 {not=} -1/3 ÷ (3/5 ÷ -7/11)

(-1/3 × 5/3) × 11/-7

= 9/-5 × 11/-7

= 99/35 {not=} -1/3 × (3/5 × 11/-7)

-1/3 × (33/-35)

-1/3 × -35/33

=35/99

i.e. 99/35 is not equals to 35/99. ANS..
