You can put this solution on YOUR website!
-5y%5E4%28y%5E5%29%5E2+%2F+15y%5E7%28y%5E2%29%5E3
Cancel the 5
= -y%5E4%28y%5E5%29%5E2+%2F+3y%5E7%28y%5E2%29%5E3
Expand
= -y%5E4%2Ay%5E10+%2F+%283y%5E7%2Ay%5E6%29
= -y%5E14%2F3y%5E13
= -y%2F3
--------------
Was your answer (-1/3)y ? That's correct.
Or, -1/(3y) ? That's wrong.
