Question

What Is The Numerical Coefficient Of Each Of The Following:

$$\begin{gathered} \left(i\right)xy \\ \left(ii\right)-6yz \\ \left(iii\right)7abc \\ \left(iv\right)-2x^3{y}^{2}z \end{gathered}$$

Answer 1

Step 1: Determine the numerical coefficient of $xy$.

There is no numerical value that is multiplied by the variables in the term $xy$.

Hence, the numerical coefficient of $xy$ is 1.

Step 2: Determine the numerical coefficient of $-6yz$.

The numerical value that is multiplied by the variables in the term $-6yz$ is $-6$.

Hence, the numerical coefficient of $-6yz$ is $-6$.

Step 3: Determine the numerical coefficient of $7abc$.

The numerical value that is multiplied by the variables in the term $7abc$ is 7.

Hence, the numerical coefficient of $7abc$ is 7.

Step 4: Determine the numerical coefficient of $-2x^3{y}^{2}z$.

The numerical value that is multiplied by the variables in the term $-2x^3{y}^{2}z$ is $-2$.

Hence, the numerical coefficient of $-2x^3{y}^{2}z$ is $-2$.
