Question

100%

Use logarithms to solve.
e2x – et – 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:
Remember by the rule of exponents, that e- * = (et)- so that you can try to factor this as
+ something) (et + something else) where the "something" and "something else" can be
(et
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 x.
