    `(15^3+5.15^2-5^3)/(15^3+6.15^2-6^3)`

    `=(5^3.  (3^3)+5.(3^2).(5^2)-5^3)/(5^3.(3^3)+3.2.(5^2).(3^2)-(2^3).(3^3))`

    `=(5^3.(3^3)+5^3.(3^2)-5^3)/(5^3.(3^3)+(3^3).(5^2)-3^3.(2^3))`

    `=(5^3.(3^3+3^2-1))/(3^3.(5^3+5^2-2^3)`

    `=(125.(27+9-1))/(27.(125+25-8))`

     `=(125.35)/(27.142)`

    `=4375/3834`

    Check xem mình sai đâu nha
