To solve this problelm you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
[tex] [ (6^{-2})(6^{5})]^{-3} [/tex]
2. So, you must apply the exponents properties. As both bases are equal, you can sum the exponents:
[tex] (6^{3})^{-3} [/tex]
3. Now, multiply the exponent [tex] 3 [/tex] by the exponent [tex] -3 [/tex], and you obtain:
[tex] 6^{-9}
[/tex]
Therefore, the answer is: B. [tex] 6^{-9} [/tex]
