Question

Which quotient does not belong with the other three? Explain your reasoning.

Answer 1

The third from the top does not belong with the others.

Explanation:

With the exception of the 3rd quotient, the expressions all involve powers of the same base. There is an exponent property that can be used in such a situation:

`(a^m)/(a^n)=a^(m-n)`

but the base, a, must be the same in both parts of the quotient!
