Question 1012159
.
Solve the following exponential equation by expressing each side as a power of the same base and then equating exponents.

9^4^x^-1=729
------------------------------------------------------------------

<pre>
{{{9^(4x-1)}}} = {{{729}}}.

Notice that 729 = {{{9^3}}}.

Thus

{{{9^(4x-1)}}} = {{{9^3}}}.

Hence,

4x-1 = 3.

Solve it yourself.
