Answer:

-343

Step-by-step explanation:

Given the expression:   [tex]\dfrac{(-7)^2}{(-7)^{-1}}[/tex]

You will notice that the terms in the numerator and denominator have the same base (-7).

This makes it very easy to simplify by applying the division law of indices.

[tex]\dfrac{a^x}{a^y} =a^{x-y}[/tex]

Therefore:

[tex]\dfrac{(-7)^2}{(-7)^{-1}}=(-7)^{2-(-1)}\\=(-7)^{2+1}\\=(-7)^3\\=-7 X -7 X -7\\=-343[/tex]
