​

Answer 1

$\sf\underline{\underline{ \large {Question :-}}}$

• The degree of the polynomial 7a⁵ + 4 a ³ + 9a ?

$\sf\underline{\underline{ \large {Answer :-}}}$

• The degree is $\sf\red{5}$.

$\sf\underline{\underline{ \large {Explanation :-}}}$

• The degree of a polynomial is the highest of the degrees of the polynomial's monomials (individual terms) with non-zero coefficients. 
• So, in the question 7a⁵ has the highest power so the degree of the polynomial 7a⁵ + 4 a ³ + 9a is $\sf\red{5}$.
