Best ResponseYou've already chosen the best response.0From the first post, and using the properties of exponents, we can rewrite the first term as: \[3^{x}3^{3}3^{x}=78\] Then, you can see that you can factor out a 3^x to get: \[3^{x}(3^{3}1) = 78\] Simplify what's inside the parenthesis to get: \[3^{x}(271)=78\]\[3^{x}(26)=78\]Divide both sides by 26 to get: \[3^{x}=3\] Now, what value of x do you need to make this statement true? 1. Why because \[3^{1}=3\] Therefore, x = 1. The end.
