Solve the equation algebraically. Round the result to three decimal places.
log4 x  log4(x1) = 1/2
I have no idea how to do this. Please help!

remember log a log b= log(a/b)
so with that..
log4 (x/(x1))=1/2
x/(x1)= 16
then solve for x. 
Greetings:
log_4[x]  log_4[x1] = 1/2 implies log_4[x/(x1)] = 1/2 which means that 4^(1/2) = x/(x1) or, 2 = x/(x1). I shall assume you can finish from there.
