Question 1207550
<pre>
We can't expect students to be familiar with the notation for this site.
Your problem should appear this way:

Please help me {{{cross(solve)}}} {{{highlight(simplify)}}} the equation {{{f(x)=-log(1/3,(root(3,x)))}}} : 
→ {{{f(x)=-log(1/3,(root(3,x)))}}} <--(Note: This is the same as what's given.
So it means this choice claims that the expression on the right cannot be
simplified.
→ {{{f(x)=-expr(1/3)log(1/3,(x))}}}
→ {{{f(x)=expr(1/3)log(3,(x))}}}

-------------------------------------------------------

{{{f(x)=-log(1/3,(root(3,x)))}}}

This tests you to see if you know that the cube root is the same as the
one-third power:

{{{f(x)=-log(1/3,(x^(1/3)))}}}

This tests you to see if you know the rule of logs that the log of an
exponential is the exponent times the log of the base:

{{{f(x)=-expr(1/3)log(1/3,(x))}}}

Which choice is that?
