The seventh-degree term refers to the term in a polynomial expression that has a degree of 7. In other words, it is the term with the highest power of the variable being raised to 7.
In a polynomial expression, coefficients are numerical constants multiplied by variables raised to various powers. For example, in $3x^2$, 3 is the coefficient.
As mentioned earlier, degree refers to the highest power of a variable in a polynomial expression. In terms of individual terms within an expression, it indicates their level or magnitude compared to others.
Leading term: The leading term is similar to the seventh-degree term but specifically refers to the highest degree (power) term in an entire polynomial expression rather than just one individual term within it.
