1. Log10²x+log10x²=log10² 2-1
2. Log4(log2x)+log2(log4x)=2
3. X^logx+5/3= 10^5+log x
4. Log 1/2(x-1)+ log 1/2(x+1)-log1/√2(7-x)=1

I put it into Wolfram the way you typed it , and the webpage interpreted it the same way I did

What a messy equation that would be to solve
I have a feeling you meant something like

X^logx + 5/3= 10^(5+log x)

looks like very messy stuff for the other equations as well, the way you typed it.

Prove that log a, log ar, log ar^2 is an a.p. Is the following below correct? Log ar^2 - Log ar= Log ar - Log a hence applying laws of logarithm Log(ar^2/ar) = log(ar/a) Log and log cancels out and then cross-multiply hence a^2r^2
