Determine if the expression 3r^5 + 8r^3 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.
The given expression ___ a polynomial.
The given expression, 3r^5 + 8r^3, is a polynomial. It is a polynomial because it is a sum of terms, each consisting of a coefficient (3 and 8) multiplied by a variable (r) raised to a non-negative integer exponent (5 and 3).
The type of this polynomial is a polynomial with two terms.
The degree of this polynomial is 5, as it is determined by the highest exponent of the variable (r) in the expression.
The given expression represents a polynomial. The polynomial is a ____(monomial, binomial, trinomial, none of the above) and has a degree of ____
.
The given expression, 3r^5 + 8r^3, is a polynomial. It is a polynomial with two terms, so it is not a monomial, binomial, or trinomial.
The degree of this polynomial is 5, as it is determined by the highest exponent of the variable (r) in the expression.
