Question

Simplify the expression so there is only one positive power for the base -5

Answer 1

When we are dividing, exponents are subtracted!

The rule is shown below:

`a^b/ a^c=a^(b-c)`

We can apply this rule to this problem as shown:

`\begin{gathered} -5^7/-5^2 \\ =-5^(7-2) \\ =-5^5 \end{gathered}`
