Step-by-step explanation:
1) 5x⁵ → The variable in the given monomial has an exponent of 5. Therefore, the degree of 5 is called quintic.
2) 6x²y → The variable with the highest degree is x², which is quadratic.
3) 9x⁵y³ → The variable with the highest degree is x⁵, which is considered as quintic.
4) 8x²y → The variable with the highest degree is x², which is considered as quadratic.
5) 15x⁷yz → The variable with the highest degree is x⁷, which is considered as septic or heptic.
