Answer:

1/5^9

Step-by-step explanation:

X^n / X^m = (X)^n-m

5^(-6-3)

5^-9

1/5^9

Best regards

For this case we have that by definition of power properties:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

Then, we have the following expression:

[tex]\frac {5 ^ {- 6}} {5 ^ 3}[/tex]

It can be rewritten as:

[tex]\frac {1} {5 ^ 6 * 5 ^ 3}[/tex]

By definition of power properties we have:

[tex]a ^ m * a ^ n = a ^ {m + n}[/tex]

So:

[tex]\frac {1} {5 ^ 6 * 5 ^ 3} = \frac {1} {5 ^ 9}[/tex]
