  • Graphical form: y%5E4%2F9%2F%28y%5E-4%2F9%2B4y%5E5%2F9%29 simplifies to y%5E4%2F9%2F%281%2Fy%5E4%2F9%2B4%2Ay%5E5%2F9%29
  • Text form: y^4/9/(y^-4/9+4y^5/9) simplifies to y^4/9/(1/y^4/9+4*y^5/9)
  • Cartoon (animation) form: simplify_cartoon%28+y%5E4%2F9%2F%28y%5E-4%2F9%2B4y%5E5%2F9%29+%29
    For tutors: simplify_cartoon( y^4/9/(y^-4/9+4y^5/9) )

DETAILED EXPLANATION

Look at y%5E4%2F9%2F%28highlight_red%28+y%5E-4+%29%2F9%2B4%2Ay%5E5%2F9%29.
Negative power changes multiplication to division
It becomes y%5E4%2F9%2F%281%2Fhighlight_green%28+y%5E4+%29%2F9%2B4%2Ay%5E5%2F9%29.
Result: y%5E4%2F9%2F%281%2Fy%5E4%2F9%2B4%2Ay%5E5%2F9%29
