First, combine like terms: $3x^5 + 8x^5 = 11x^5$ and $7x^4 + 3x^4 = 10x^4$. Then, arrange in descending order to get $11x^5 + 10x^4$.

Collect Like Terms and Then Arrange in Descending Order 7x4+3x5+3x4+8x57 x^{4}+3 x^{5}+3 x^{4}+8 x^{5}7x4+3x5+3x4+8x5

Collect Like Terms and Then Arrange in Descending Order $7 x^{4}+3 x^{5}+3 x^{4}+8 x^{5}$
