Final answer:
The value of a when rewriting (6/17)^9 x as a^x is (6/17)^9.
Step-by-step explanation:
To find the value of a when we rewrite (6/17)^9 x as a^x, we are looking for a base a that can represent (6/17)^9 raised to the power x. To achieve this, we recognize that (6/17)^9 can be the value of the base a. Therefore, the expression (6/17)^9 x is the same as a^x, where a is equal to (6/17)^9.
