Question

what is the coefficient of the second term in this expression?
3k² + m²n³ - 5km²

Explanation:

Step1: Identify the second term

The expression is \(3k^{2}+m^{2}n^{3}-5km^{2}\). The terms are separated by addition or subtraction signs. So the first term is \(3k^{2}\), the second term is \(m^{2}n^{3}\), and the third term is \(- 5km^{2}\).

Step2: Determine the coefficient of the second term

The coefficient of a term is the numerical factor (including the sign) of the term. For the term \(m^{2}n^{3}\), we can think of it as \(1\times m^{2}n^{3}\) (since when a variable or a product of variables has no written coefficient, the coefficient is 1). So the coefficient of the second term \(m^{2}n^{3}\) is 1.
