Answer:
[tex]a = 8.498\times 10^{-5}[/tex]
Step-by-step explanation:
The value of [tex]a[/tex] is obtained herein:
[tex]\left(\frac{6}{17} \right)^{9\cdot x}[/tex]
[tex]\left[\left(\frac{6}{17} \right)^{9}\right]^{x}[/tex]
[tex]\left(8.498\times 10^{-5} \right)^{x}[/tex]
[tex]a = 8.498\times 10^{-5}[/tex]
