The equation is

$64(12)^{8x} = 195$

the steps I have done so far.

  • $12^{8x} = 195/64$
  • $8x \cdot \ln(12) = \ln(195/64)$
  • $8x = (\ln(195/64))/(\ln(12))$

not sure how to divide $8x$ to get $x$ by itself for the final answer with the ln's

when you divide $8x = (\ln(195/64))/\ln(12)$ you get $x = (\ln(195/64))/(\ln(12)(8))$. The 8 only affects the bottom denominator of equation when you divide a fraction. thank you @GerryMyerson
