3%2Asqrt%28log%28x%29%29%2B2%2Asqrt%28log%281%2Fx%29%29=2


Remember that %28log%28x%29%29%5Ey+=+y+%2A+log%28x%29


%283%2F2%29%2Alog%28x%29%2B+log%281%2Fx%29=2


Remember that log(x/y) = log(x) - log(y) and log(1)=0


%283%2F2%29%2Alog%28x%29%2B+log%281%29+-+log%28x%29=2


%283%2F2%29%2Alog%28x%29+-+log%28x%29=2


%281%2F2%29%2Alog%28x%29+=+2


log(x) = 4


Remember that log(basex)(y) = a if and only if x%5Ea+=+y


log means log base 10.


10%5E4+=+x+=+10000
