Best ResponseYou've already chosen the best response.0To explain this with words, think of 2^m = 8. This would be 3, no? Then to get to 1/8, simply make the exponent negative.

Best ResponseYou've already chosen the best response.0\[2^m =\frac{1}{8}\]You need to solve for m, thus eliminating the base, taking \(\log_2\) of both sides, as @IrishBoy123 said would simplify the left side, therefore solving for m. \(\log_2(2) = 1\) \[\log_2(2^m) = \log_2\left(\frac{1}{8}\right)\]
