Question 1129080
<br>
You are asked, when you submit a question, to show any work you have done to try to solve the problem.  That way, we can help you see what you did wrong.  That is a lot more helpful to you than just having us show you how to do the problem.<br>
I'll set up the problem for you; you can finish solving it and compare it to the work you did earlier to try to see your error....<br>
{{{27 * 3^(7x) = 9}}}<br>
Put everything in powers of 3:<br>
{{{(3^3)*(3^(7x)) = (3^2)}}}
{{{3^(3+7x) = 3^2}}}<br>
The bases are the same; so the exponents are equal.  Solve the equation that says the powers of 3 on the two sides of the equation are equal.
