Combine like terms: $5n^5 + 8n^5 = 13n^5$, $-9n^3 - 3n^3 = -12n^3$, and $9n + 4n = 13n$.

Add or Subtract as Indicated (5n5+9n−9n3)+(−3n3+8n5+4n)\left(5 n^{5}+9 n-9 n^{3}\right)+\left(-3 n^{3}+8 n^{5}+4 n\right)(5n5+9n−9n3)+(−3n3+8n5+4n)

Add or Subtract as Indicated $\left(5 n^{5}+9 n-9 n^{3}\right)+\left(-3 n^{3}+8 n^{5}+4 n\right)$
