#### Answer

$b^3+b^2+3$, cubic trinomial

#### Work Step by Step

To put a polynomial into standard form, we move around the terms so that their exponents are in descending order and then combine like terms using addition. When we do this for $3+b^3+b^2$, we get $b^3+b^2+3$. To name a polynomial, we must look at the degree and the number of terms. Since this polynomial has $3$ terms with a highest exponent of $3$, we call it a cubic trinomial.
