Hello, Originally Posted by SVXX This equation has me at loggerheads... Even a hint would be appreciated! Note that So And Multiply by ln(x), and ln(4) if you want to, then susbtitute y=ln x
We haven't done natural logarithms in class yet, LOL. Could I get some further tips for this? Or is there any other way to solve it?
Ok... There is a formula : (took it from Wikipedia) Taking and , you get : So now you're working on base 4 This time, multiply by
If I take as y, it will turn out to be a quadratic equation. So I guess we'll have two answers... The roots for y are 1.5 and 0.3333. Taking y = 1.5, 4 raised to 3/2 or 1.5 is x, or x = 8. Merci beaucoup, Madame :P
