Question

what is the variable in 8y3 ?

Answer 1

8y3

8 the coefficient. 8 is a factor (used to multiply)

y a variable. That is, y had an unknown value that may change (vary) over time. For example, a person's age changes over time, so it is a variable.

3 Perhaps this is 8y³. That means that 3 is an exponent. The expression is really 8*y*y*y. The 3 allows us to write it in a shorter form (since there are 3 y's).

Answer 2

A variable is just an unknown quantity. In math we use letters to stand for unknown quantities. Coefficients are numbers that are in front of variables. Exponents are numbers that are smaller and written above coefficients or variables. I won't tell you the answer, and hopefully I have given you enough information to answer the question.
