use log a+log b=log ab and log a log b= log (a/b)

ok, can I just check the equation is it 1. \[2 \log(4)  \log(3) + 2\log(x)  4 = 0\] or 2. \[2 \log(4)  \log(3) + 2\log(x  4) = 0\]

thus here we have 2 log 4 – log 3 + 2 log x – 4 =0 or log (4^2*x^2 )/3 = 4 [nlog a =log a^n] and log 1=10 as the base must be 10 here ]

@campbell_st Honestly I'm not really sure. It's a question for my online school and it doesn't specify what it is, but I'm assuming it's (x4). I guess we can know which it is if there's no answer choice.

2 log 4 – log 3 + 2 log x – 4 =0 log (4^2*x^2 )/3 = 4 log (4^2*x^2 )/3 =4 log 10 [as log10=1] log (4^2*x^2 )/3 = log 10000 or 16x^2/3 =10000 or x^2 =10000/16 *3 or x^2 =1875 hence x=sqrt(1875) =43.3013
