What does the coefficient of a quantity tell us?
Coefficients record the number of like
terms in an algebraic expression.
Exponents record the number of like
factors in a term.
In a term, the coefficient of a particular group of factors is the remaining group of factors.
how many of that quantity there are
.
The coefficient of is 3; the coefficient of is ; and the coefficient of 3 is .
.
The coefficient of is 4; the coefficient of 4 is ; and the coefficient of is since can be written as .
