Question 24831
<pre><b>the equation i have is {{{ log( r, -107/64 = 6) }}}   .
i'm not sure how to set it up so that i can find the r base of the log.

     107
log<sub>r</sub>————— = 6
      64

Use this rule of logarithms to rewrite that equation

log<sub>B</sub>A = C means the same thing as B<sup>C</sup> = A

      107
r<sub>6</sub> = —————
       64

Taking positive sixth roots of both sides:
