log16log3+logx^2=4 log[(16+x^2)/3]=4 (16+x^2)/3=10^4 16+x^2=3*10^4 x=sqrt(3*10^416)

if you are asking this 2 log 4 – log 3 + 2 log( x – 4) = 0 then log16log3+log(x4)^2=0 log[(16+(x4)^2)/3]=0 (16+(x4)^2)/3=10^0=1 16+(x4)^2=3 (x4)^2=13 no real solution..

Ohhhhh that makes much more sense, the first one and yeah we just made the mistake of using a calculator which I realize now doesn't work for something with x in it, so we got completely the wrong answer. Thanks for your help!
