Question

What is the coefficient of term $x{y}^3$ in the expression $5x^3+10x{y}^3$ ?

• A. 10x
• B. 10
• C. -10
• D. -1

Answer 1

The correct option is B

10

The coefficient of term $x{y}^3$ in the expression $5x^3+10x{y}^3$ is 10.

A coefficient may be either a numerical factor (like 5, -3, 25...) or an algebraic factor (like $x,y,x^{3}y$...) or a product of two or more factors (like $3xy,5x^{2}z$...) in a term of an algebraic expression.

$\therefore$ The coefficient of $x{y}^3$ in the expression $5x^3+10x{y}^3$ is 10
