One "simplifies" expressions; one "solves" equations. Which do you have? Also:
B) Does this mean \(\displaystyle 12^{\log_{12}{(2\,+\,8q)}}\), or something else?
C) Does this mean log<sub>256</sub>(16<sup>k</sup>), or something else?
D) Does this mean \(\displaystyle \L 5^{\left(5\log_5{8}\, - \,8\log_5{5}\right)}\), or something else?
When you reply, please include all of the steps you have tried so far. Thank you.
