Hi,
Can anyone show me the workings a few log equations? I can't seem to be able to get the answer.
Qns: Solve the following equation,
1.
\(\displaystyle 6 + \log_{2}x = (\log_{2}x)^2\)
My Working:
\(\displaystyle 6 + \log_{2}x = (\log_{2}x)^2
\log_{2}x - (\log_{2}x)^2 = -6\)
Problem: I am stuck at the second line because i don't know how to remove the square root of \(\displaystyle (log_{2}x)^2\)
2.
\(\displaystyle \log_{2}(x+4) - \log_{4}x = 2\)
I do not know how to write "ln" symbol and (x + 4)/x in Tex so i am sorry if i did not put my working. I am not sure if i did my working correctly, so if someone can show me how it is done.
Thanks
