Question

Identify the numerical coefficient of $p$ in $-78pr{z}^2$

• A. 78
• B. $-78r{z}^2$
• C. $-78$
• D. $78z^2$

Answer 1

The correct option is C $-78$

Any factor or group of factors of a product is known as the coefficient of the remaining factors.
In the product $-78pr{z}^2$: the coefficient of $p$ = $-78r{z}^2$
However the numerical cofficient is only -78, as this is the only factor which is a numerical quantity. The remaining are literal coefficients of $p$.
