What is the solution to the equation log [2] x – log [2] 4 = 2 ?
i got x=18 but I wanted another opinion
I dont think thats correct, what did your equation look like before your answer?
that is supposed to be a sixteen
\[\log_2 x - \log_2 4 =2\] \[\implies \log_2 (\frac x4) = 2\] change to expoenntial form \[\implies 2^2 = \frac x 4\] simplify... \[\implies 4 = \frac x4\] cross multiply \[\implies 4 \times 4 =x\] simplify.. \[\boxed{\implies 16 = x}\]
Ohhh. Okay I see exactly what I did wrong. I really appreciate it..!
