Use logarithms to solve. e2x – ex – 56 = 0 Enter the exact answer (i.e. keep your answer in exponential or logarithmic form, you do not need to calculate its numeric value). Enclose arguments of functions in parentheses and include a multiplication sign between terms. For example, c * In (h). Hints: = (e")² so that you can try to factor this as • Remember by the rule of exponents, that e2 (et + something) (eT + something else) where the "something" and "something else" can be * positive or negative numbers. • Alternately, you could let y = eT and this equation would be y2 – y – 56 = 0 and you can solve first for y and then for æ. x =
