Write the coefficient of x² in the following: y + y²x + y³x² + y⁴x³

Solution:

Given, the expression is y + y²x + y³x² + y⁴x³

We have to find the coefficient of x² in the given expression

Coefficient is the numerical factor in a term.

Sometimes, any factor in a term is called the coefficient of the remaining part of the term

From the expression,

We observe that y³x² = y³ × x²

Therefore, the coefficient of x² is y³.
