Answer:
The simplified form of this is 6^-9
Explanation:
In order to find this, we first complete the operation inside the parenthesis. In this case, since it is multiplication, we add the exponents.
6^-2 x 6^5 = 6^3
Now that we have the simplified inside we multiply exponents using the parenthesis.
(6^3)^-3 = 6^-9
