The answer is x=9

Explanation:

First simplify it. Since when you multiply exponents you can add them, thats how you simply

2/3^x+2/3^9=2/3^18

Ok now that we simplified as much as we can, we can remove the base since they all have the same base. (The base is 2/3) so the equation is now:

x+9=18

Now just solve for x

x+9=18 subtract 9 from both sides
x=9
