Question

How do i solve (log base 2 of x)^2-3log base 2 of x-10=0

Answer 1

\[\huge (\log_2 x)^2-3\log_2 x - 10\] If the logs are throwing you off, try thinking of them as a single variable, it might make it easier to recognize what is going on.\[\large u^2-3u-10=0\]The first step is realizing that it's just a quadratic that you can toss into the quadratic function.

Answer 2

ah, thank you very much, I forgot about substituting u, (2 chapters ago, lol) thanks again. It makes sense now
