Question 1015517
<pre>
{{{2*log((x))}}}{{{""=""}}}{{{20}}}

Divide both sides by 2

{{{log((x))}}}{{{""=""}}}{{{10}}}

When the base of a logarithm is not written, it
is understood to be 10.

{{{log(10,(x))}}}{{{""=""}}}{{{10}}}

Use the principle that the logarithm equation {{{log(B,(A))=C}}} is
equivalent to the exponential equation {{{A=B^C}}}

{{{x}}}{{{""=""}}}{{{10^10}}}

{{{x}}}{{{""=""}}}{{{10000000000}}}
