Answer:

$ y^6 $

Step-by-step explanation:

$ \frac{a^b}{a^c} = a^{b - c} $

Using this rule we have:

$ \frac{y^{-7}}{y^{-13}}  = y^{-7 -(-13)} = y^6$

Answer:

  y^6

Step-by-step explanation:

The applicable rules of exponents are ...

  y^ay^b=y^{a+b}\\\\\dfrac{1}{y^{-a}}=y^a

Using these rules, you can write the expression as ...

  \dfrac{y^{-7}}{y^{-13}}=y^{-7-(-13)}=y^6
