Question

what is the coefficient of the first term in this expression?
d³ + bd³

Explanation:

Step1: Identify the first term

The expression is \( d^3 + bd^3 \), so the first term is \( d^3 \).

Step2: Recall the definition of coefficient

A coefficient is the numerical factor of a term. For the term \( d^3 \), we can write it as \( 1 \times d^3 \) (since any number multiplied by 1 remains the same). So the coefficient of \( d^3 \) is 1.
