-logx=21.1 logx=-21.1 e^-21.1=x
logx = 2 so x = 10logx = 102 = 100 ie x = 100.
You can't solve this since it isn't an equation.There is also an ambiguity (it's hard to write math on a typewriter keyboard) - are we talking about log(x3) or maybe logx(3)?Restate the question: Simplify log(x3)Answer: 3log(x)You could explain this by saying: log(x3) = log[(x)(x)(x)] = logx + logx + logx = 3logx. The general rule is log(xn) = nlogx.
logx=12 x=10^12 x=1,000,000,000,000
log3 + logx=4 log(3x)=4 3x=10^4 x=10,000/3
