4 log 16 For example, in the problem given, by rewriting 16 as a power of 4, we made it easier to solve the equation. Once the bases match, equate the exponents and solve it like a regular algebra. Rewrite log(16) log (16) as log(24) log (2 4). Expand log(24) log (2 4) by moving 4 4 outside the logarithm. Rewrite log(4) log (4) as log(22) log (2 2). Expand log(22) log (2 2) by moving
4dcrot, 14 Explanation: Remember that displaystyle{16}={2}^{{4}} : displaystyle{{log}_{{16}}{left({2}rht)}}={{log}_{{16}}{left({16}^{{frac{{1}}{{4}}}}rht)}}=frac{{1}}{{4}}.
