Question 250010
{{{2^log(2,(8x-1))}}}
<pre><font size = 4 color = "indigo"><b>
Let it equal to M:

{{{2^log(2,(8x-1))=M}}}

Use the fact that {{{B^A=C}}} can be written as {{{log(B,C)=A}}}
to rewrite that

{{{log(2,(M)) = log(2,(8x-1))}}}

Then since the logs are equal, what they are the logs of are
also equal, so we get

M = 8x-1

so the answer is 8x-1
