Question

16y5+4y5-12y3+15y3?
What is the simplified form?

Answer 1

`20y^(5) +3y^(3)`

Explanation:

`16y^(5) +4y^(5) =20y^(5)` and
`-12y^(3) +15y^(3) =3y^(3)`

So
`20y^(5) +3y^(3)`

Answer 2

`20y^5+3y^3`

Explanation:

`16y^5 + 4y^5 -12y^3 + 15y^3`

All we can do here is combine like terms (add those that have the same the same exponent)

`20y^5+3y^3`

Good luck!
